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.
