Question

For a car there are 5 tyres including one spare tyre (4+1). all tyres are equally used. if the total distance travelled by the car is 40000 km then what is the average distance travelled by each tyre?

Answer 1

total distance travelled by the car=40000km
so total distance travelled by 4 wheels=4*40000=160000
as all tyres(4+1) are equally used
so average distance travelled by the each tyre=160000/5=32000

Answer 2

Answer:

Step-by-step explanation:

Let's break it down.

We know that all the tyres traveled same distance, how is it possible?

imagine this first, the person will travel 1 km with four tyres attached to car,

replace one tire with left out tyre, travel one more km, do the same (travel one more km by replacing the new left out tyre.)

after 5 kms of journey of car each tyre has traveled 4 kms.

Car dis.           tyre dist.

5 km            -     4 km

40,000 km  -      X

X = 32,000 km.
