Question

What is the average speed of

a. an aircraft which travels 600 m in 10 seconds?
b. An athlete who runs 1000 m in 2 minutes?

Answer 1

Average Speed ( Velocity ) = [ Distance traveled ] ÷ [ time of the traveled distance in seconds ]

_______________________________

a .

AS = 600 ÷ 10

AS = 60 m/s

______________________________

b .

2 minutes = 2 × 60 = 120 seconds

AS = 1000 ÷ 120

AS = 100 ÷ 12

AS = 25 ÷ 3

AS = 25/3 = 8.33 m/s ( approximately )
