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
