Question

if there are 125 km of streets to be patrolled by 5 police cars how many kilometers must each car cover

Answer 1

Task. If there are $d=125$ km of streets to be patrolled by $n=5$ police cars how many kilometers must each car cover.

Solution. Assume that cars patroll equal distances. Then one car should cover the distance

$\frac{d}{n}=\frac{125}{5}=25~{}km.$
