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

$t=\frac{5}{60}hr$

$d_1=s*t$

now, we can plug values

$d_1=12*\frac{5}{60}$

$d_1=1$

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

$t=\frac{8}{60}hr$

$d_2=s*t$

now, we can plug values

$d_2=17*\frac{8}{60}$

$d_2=2.26667$

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

$t=\frac{2}{60}hr$

$d_2=s*t$

now, we can plug values

$d_3=6*\frac{2}{60}$

$d_3=0.2$

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

Step-by-step explanation:

The polar bears had 2,208 fish (48 piles times 46 fish).

The penquins had 3,312 fish (144 piles [48 times 3] times 23 fish [46 divided by 2]).

2208 fish plus 3312 fish equals 5,520 fish.
