Question

a red car travels 400 m in 20 s a blue car travels 660 m in 30 s. which car has the greater average speed.

Answer 1

average speed of red car = 400/20=20 m/sec

average speed of blue car =660/30=33 m/sec

so blue car moves with more average speed

Answer 2

Speed of red car = d/t

= 400/20

= 20 m/s

Speed of blue car = d/t

= 660/30

= 22 m/s

Therefore, the average speed of the blue car is more than that of the red car.

22 > 20
