A man always keeps a spare tyre in his car. To make full use of all the five tyres, he changes the tyres in a manner that for a distance of 1, 00,000 km, each of them runs the same distance.

Can you calculate the distance traveled by each tyre in that journey ?

80,000.

We need to calculate the 4/5th of the total distance to solve the problem.

4/5 * 1, 00,000 km = 80, 000 km

Thus, each tyre traveled 80, 000 km.
