The sum of two consecutive mile markers on the interstate is 331. Find the numbers on the markers

165 and 166

Step-by-step explanation:

Let two consecutive mile markers be x and x+1.

According to the question,

x+x+1=331

2x = 331-1

2x = 330

x = 165

So, the number be 165 and 166.

The total nom of  code that can be used is equal to 5+3 = 8

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The answer is in the image 

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
