Question

Suppose you have a scooter that has two tires and one stepni (spare tire). Each tire can run 50 km. How long can a scooter run?

The scooter has three tires, and each tire can run 50 kilometers, then the total distance they can cover is 150 km. However, at any time, we need 2 tires. Hence, the total maximum distance that you can cover by your scooter is = 150/2 = 75 kilometers.

Answer 1

Explanation: Let's see how the maximum distance would be achieved. Let the three tires be A, B, and C.

The total distance covered on tires A and B would be 25 kilometers (remaining: tire A capacity = 25 km, tire B capacity B = 25 km, tire C capacity = 50 km)

The total distance covered on tires B and C would be 25 kilometers (remaining: tire A capacity = 25 km, tire B capacity = 0 km, tyre C capacity = 25 km)

The total distance covered on tires A and C would be 25 kilometers (remaining: tire B capacity = 0 km, tire B capacity B = 0 km, tire C capacity = 0 km).

The total distance covered is: 25+25+25 = 75 km.
