Distance biked by Mike = 3 1/2 mi = 3.5 mi 

Distance biked by Noah = 5 1/4 mi = 5.25 mi 

Distance biked by Noah/Distance biked by Mike = 5.25/3.50

Distance biked by Noah/Distance biked by Mike = 21/14 = 3/2

Distance biked by Noah = 3/2 times distance biked by Mike

Option B

2 times the length of Noah's bike ride was Mai's bike ride

Solution:

Given that Mai biked 7 and 1/4 miles today and Noah biked 3\frac{5}{8} miles

We have to find how many times the length of Noah's bike ride was Mai's bike ride

Let "a" be the number that denotes how many times the length of Noah's bike ride was Mai's bike ride

From given information,

Distance biked by Mai = 7\frac{1}{4} \text{ miles}

Distance biked by Noah = 3\frac{5}{8} \text{ miles}

So to find how many times the length of Noah's bike ride was Mai's bike ride, we can frame a equation as:

"a" times distance biked by noah is equal to distance biked by mai

\text{ Distance biked by Mai } = a \times \text{ Distance biked by Noah }

Substituting the known values we get,

7\frac{1}{4} = a \times 3\frac{5}{8}\\\\\frac{4 \times 7+1}{4} = a \times \frac{8 \times 3 +5}{8}\\\\\frac{29}{4} = a \times \frac{29}{8}\\\\\frac{1}{4} = \frac{a}{8}\\\\a = 2

Thus 2 times the length of Noah's bike ride was Mai's bike ride

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
