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
[tex] t=\frac{5}{60}hr [/tex]
[tex] d_1=s*t [/tex]
now, we can plug values
[tex] d_1=12*\frac{5}{60} [/tex]
[tex] d_1=1 [/tex]
second distance:
speed =17 kh/hr
time=8 minutes
we can change into hour
[tex] t=\frac{8}{60}hr [/tex]
[tex] d_2=s*t [/tex]
now, we can plug values
[tex] d_2=17*\frac{8}{60} [/tex]
[tex] d_2=2.26667 [/tex]
third distance:
speed =6 kh/hr
time=2 minutes
we can change into hour
[tex] t=\frac{2}{60}hr [/tex]
[tex] d_2=s*t [/tex]
now, we can plug values
[tex] d_3=6*\frac{2}{60} [/tex]
[tex] d_3=0.2 [/tex]
now, we can find total distance
[tex] d=d_1+d_2+d_3 [/tex]
[tex] d=1+2.26667+0.2 [/tex]
[tex] d=3.46667 [/tex]
so,
total distance is 3.46667 km...........Answer
