Question 35 Fractions Exercise 2B

A car covers a certain distance at a uniform speed of [66(2/3)] km per hour. How much distance will it

cover in 9 hours?

Answer:

Solution:-

From the question,

The total distance covered by a car in 1 hour = [66(2/3)] km = (200/3)

Therefore, the distance covered by a car in 9 hour = (200/3) × 9

Then,

= (200/3) × (9/1)

= (200 × 9) / (3 × 1)

On simplifying we get,

= (200× 3) / (1 × 1)

= 600 km

Hence, the distance covered by a car in 9 hours is 600 km.
