Question

Victoria currently walks to school from her apartment, which is 1.1 miles away from her first class. She typically walks at a speed of 2 miles per hour. She is considering buying a used bicycle from Deseret Industries to ride to campus. Victoria assumes that if she were riding a bike, she could go about 7 miles per hour. How many minutes could Victoria save getting to class each morning if she were to ride the bike?

Answer 1

Answer:

She will save 23.574 minutes

Step-by-step explanation:

We have given that when she walks to school from her apartment which is 1.1 miles away from her apartment speed is 2 miles per hour

So distance d = 1.1 miles

And speed = 2 miles per hour

We know that $time=\frac{distance}{speed}=\frac{1.1}{2}=0.55hour$

It is also given that when she ride a bike her speed is 7 miles per hour

So $time=\frac{distance}{speed}=\frac{1.1}{7}=0.1571hour$

So time saving = 0.55 - 0.1571 = 0.3929 hour

We know that 1 hour = 60 minutes

So time saving $=0.3929\times 60=23.574minutes$
