On a bicycle, Jane rides for 9 hours and is 47 miles away from her house. After riding for 11 hours, she is 57 miles away. What is Jane's rate over the last 2 hours?

Question

I'm stuck on this question and I need help. Can anyone help me?

Answer 1

Hi Bethannie. In the last two hours, (which you get from 11-9), Jane is 10 miles further away from her house (57-47). So in the last 2 hours, her rate is 5 miles per hour. You get that by dividing the 10 miles by the 2 hours.

So 5 miles per hour is the answer.

Answer 2

Hi Bethannie. Since your given two times, 9 and 11, you can subtract those to get a two hour difference. The miles traveled for the two times are 47 miles and 57 miles respectively. Subtract these two to get a 10 mile difference over the 2 hours. Take 10 miles and divide by 2 hours to get 5 miles per hour.
