Randall’s family drove to the beach for vacation. they drove the same speed throughout the trip. the first day, they drove 130 miles in 2 hours. the second day, they drove 325 miles in 5 hours. the third day, they arrived at the beach after driving for 6 hours. how many miles did they drive on the third day?

Step-by-step answer

P Answered by PhD

390 miles.

Step-by-step explanation:

Randall's family drove to the beach for vacation.

The first day, they drove 130 miles in 2 hours.

Speed = $\frac{Distance}{Time}$

= $\frac{130}{2}$

= 65 miles / hour

The second day, they drove 325 miles in 5 hours

= $\frac{325}{5}$ = 65 miles/hour

The third day, they arrived at the beach after driving for 6 hours.

Distance = Speed × Time

= 65 × 6

= 390 miles.

They drove 390 miles on the third day.

Randall’s family drove to the beach for vacation. assume they drove the same speed throughout the trip. the first day, they drove 130 miles in 2 hours. the second day, they drove 325 miles in 5 hours. the third day, they arrived at the beach by driving miles in 6 hours.

Step-by-step answer

P Answered by PhD

390, you have to half 130 to get the miles travelled in an hour then times by 6 to get the miles in 6 hours

Step-by-step answer

P Answered by PhD

390 miles

Step-by-step explanation:

They drove the same speed throughout the trip means a constant speed.

A constant speed means that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

$v= \frac{x - xo}{t -to}$

where x is distance and t time. The subtract is final value minus initial value

In the first day

$v= \frac{130 miles}{2 hours} = 65 mph$

if is the same speed then for the second day it must be equal, in fact

$v= \frac{325 miles}{5 hours} = 65 mph$

Now, we have the speed and time, then

x=v * t = 65 miles/h (mph) * 6 h = 390 miles

Step-by-step explanation:

The key for this assignment is look at the units and values given. What is the desired units/value? You could also use d = r*t assuming a constant rate.

1.) If you look at the units for distance and time, and you know you want m/s for speed, then you can see division would be solution.

d = rt

40 = r(10)

r = 40/10

2.) d = rt

425 = (50)t

t = 8.5s

3.) d = rt

d = (35.25)(4)

d = 141km

4.) Add the distances together by using the equation twice for the way there and back.

216 = (48)t

t = 4.5

216 = (54)t

t = 4

4.5 + 4 = 8.5 hours

5.) Do the same thing from problem number four

210 = r(3.5)

r = 60m/h

130 = r(2.5)

r = 52mi/h

Average means the sum of the values divided by 2

0.5(60+52) = 56mi/h

P Answered by Studen AI

The impact of the narrator's statement "And here we aren't, so quickly" on the passage as a whole is that it reveals the narrator's reflection on their life in a nostalgic and regretful manner. It suggests that time has passed by quickly, and the narrator is contemplating missed opportunities and the things that could have been. The statement conveys a sense of longing and sadness, as the narrator expresses disappointment about the unfulfilled potentials in their life. It indicates that the passage explores themes of lost time, missed connections, and the fleeting nature of existence. The narrator's reflection on their past highlights the importance of cherishing the present moment, as it's a reminder that life passes by quickly and that we should make the most of each experience. Therefore, option D, "It reveals that the narrator is looking back on their life while grieving their partner's death," is the most accurate interpretation of the impact of the statement on the passage as a whole.
