Question

A car traveled 200 kilometers in 3 hours. If the car travels at the same average rate, how far will the car travel in 9 hours?

Answer 1

Answer: 600 km

Explanation:

We need to apply the concept of Time speed distance here.

When speed is constant, T ∝ D

D = S*T

200 km = 3hrs

X km = 9hrs

X = 200*9/3

= 200*3

= 600km

Answer 2

Answer: 600km

Explanation:

Using the concept of proportion, with the same average rate,

3 hours -> 200 km

9 hours -> A km

Hence,

9/3 = A/200

A = 200 x 9/3 = 200 x 3

= 600
