Question

To cover a distance of 216 km in 3.2 hours, what should be the average speed of the car in meters/second?

A) 67.5 m/s B) 33.75 m/s C) 37.5 m/s D) 18.75 m/s

Answer 1

Answer: D) 18.75 m/s

Step-by-step explanation:

Required speed of car = DISTANCE/TIME

= (216/3.3) Km/h

= (216/3.3) x (1000/3600) m/s            or                (216/3.3) x(5/18) m/s

= 18.75 m./sec.
