Question

A car travels first 10 km in 20 minutes and another 10 km in 30 minutes. What is the average speed of the car in m/s?

Answer 1

Answer:

The average speed of the car is 6.66 m/s.

Explanation:

$Average Speed=\frac{TotalDistance}{TotalTime}$

$Average Speed=\frac{(10+10)*1000}{(20+30)*60}$

$Average Speed=\frac{20*1000}{50*60}$

$Average Speed=\frac{20000}{3000}$

$Average Speed=\frac{20}{3}$

$Average Speed=6.66m/s$

Answer 2

Explanation:

The average speed = 6.66 m/s
