Question

Jen and Kamlee are walking to school. After 20 minutes, Jen has walked 4/5 mile. After 25 minutes, Kamlee has walked 5/6 mile. Find their speeds in miles per hour. Who is walking faster?

Answer 1

Answer:

speed=d×t

I'm getting 0.2 for both

not 100%

Answer 2

Answer:  Jen's speed is 2.4 miles per hour and Kamlee's speed is 2 miles per hour. So, Jen is walking faster.

Step-by-step explanation:  Given that Jen and Kamlee are walking to school. After 20 minutes, Jen has walked $\dfrac{4}{5}$ miles and after 25 minutes, Kamlee has walked $\dfrac{5}{6}$ mile.

We are to find their speeds in miles per hour and to check the one who is walking faster.

We know that

$speed=\dfrac{distance}{time}.$

So, the speed of Jan is given by

$S_J=\dfrac{\frac{4}{5}}{\frac{20}{60}}~\textup{miles per hour}=\dfrac{4}{5}\times\dfrac{60}{20}=\dfrac{12}{5}=2.4~\textup{miles per hour}.$

and the speed of Kamlee is given by

$S_K=\dfrac{\frac{5}{6}}{\frac{25}{60}}~\textup{miles per hour}=\dfrac{5}{6}\times\dfrac{60}{25}=2~\textup{miles per hour}.$

Thus, Jen's speed is 2.4 miles per hour and Kamlee's speed is 2 miles per hour. So, Jen is walking faster.
