Question

A speed camera records a van travelling 60 metres in 3 seconds. Calculate the average speed of the van in miles per hour.​

Answer 1

Average speed = total distance/ total time

Average speed = 60/3 = 20 m/s

20 m/s to miles/hr

=> (20 / 1609) / (1 / 3600)

=> 0.0124 × 3600

=> 44.7 miles / hr
