The cyclist traveled 60 km between the villages in 5 hours, and on the way back his speed was 5 km / h more. How long did it take to get back?
First of all, we need to find the speed of the cyclist with which he rode to the village, for which we divide the distance between the villages known by the condition by the travel time:
60: 5 = 12 (km / h).
It is also known from the condition that on the way back his speed was 5 km / h more, that is, on the way back, the cyclist’s speed was equal to:
12 + 5 = 17 (km / h).
Let’s determine the time that the cyclist spent on the return journey:
60: 17 = 3.5 (h).
Answer: the cyclist got back in about 3.5 hours.
