Question

Jimmy is trying to escape Jane.... He runs 12 km/hr for 5 minutes, 17 km/hr for 8 minutes, and finally 6 km/hr for 2 minutes. What total distance did Jimmy run?

Answer 1

we are given

Jimmy is trying to escape Jane

For finding total distance , we will find distances and then add them

He runs 12 km/hr for 5 minutes

First distance:

speed =12 kh/hr

time=5 minutes

we can change into hour

`t=(5)/(60)hr`

`d_1=s*t`

now, we can plug values

`d_1=12*(5)/(60)`

`d_1=1`

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

`t=(8)/(60)hr`

`d_2=s*t`

now, we can plug values

`d_2=17*(8)/(60)`

`d_2=2.26667`

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

`t=(2)/(60)hr`

`d_2=s*t`

now, we can plug values

`d_3=6*(2)/(60)`

`d_3=0.2`

now, we can find total distance

`d=d_1+d_2+d_3`

`d=1+2.26667+0.2`

`d=3.46667`

so,

total distance is 3.46667 km...........Answer
