Question

Kiran and Clare live 24 miles away they start walking at 8 am Clare is walking 3.4 miles per hour and they get there at 10:30 am how fast was Kiran jogging

Answer 1

Kiran is jogging at 9.6 miles per hour.

Explanation:

We can find the speed of Kiran as follows:

`v = (x)/(t)`

Where:

v: is the speed =?

x: is the distance = 24 miles

t: is the time

If Clare and Kiran started walking at 8 am and they get to their destination at 10:30 am, then the time is:

`t = 10:30 - 8:00 = (10 h + 30min*(1 h)/(60 min)) - 8 h = 2.5 h`

Then, the speed of Kiran is:

`v = (x)/(t) = (24 miles)/(2.5 h) = 9.6 miles/h`

Therefore, Kiran is jogging at 9.6 miles per hour.

I hope it helps you!
