Question

A man's car has 5 tires (4 in regular use and 1 stepney). The car has travelled a total of 10000 km. During this period, to ensure an even amount of wear and tear on each of the 5 tires, he has been changing the tires regularly, so all tires have traveled an equal number of km. How many km has each tire traveled?

Answer 1

I think it is 2000 km

Answer 2

Answer:

Each tire traveled 8000 km.    

Step-by-step explanation:

Given : A man's car has 5 tires (4 in regular use and 1 stepney). The car has traveled a total of 10000 km.

During this period, to ensure an even amount of wear and tear on each of the 5 tires, he has been changing the tires regularly, so all tires have traveled an equal number of km.

To find : How many km has each tire traveled?

Solution :

A man's car with 4 tires traveled a total of 10000 km.

i.e. Using 4 tires at a time over 10000 km is given by

$4\times 10000=40000$ tire-km.

Which means 5 tires traveled 40000.

1 tire traveled = $\frac{40000}{5}= 8000$ km.

Therefore, Each tire traveled 8000 km.
