Question

12. A road race is 15 kilometers long. After the starting line, there are water stations every

0.3 kilometer. How many water stations are there?

Answer 1

50

Explanation:

Given

there is 1 water station at every 0.3 KM

If there are n water stations at every 0.3 KM

then KM covered by them = n*0.3 = 0.3n

given that total KM covered is 15 km

Thus,

0.3n = 15

=> n = 15/0.3 = 50

Thus, there are 50 water stations.
