Question

4. Calculate the speed of a car that covers a distance of 150 km in 3 h.​

Answer 1

Explanation:

Speed = D/T

Speed = 150/ 3

= 50 km/h

IN m/s = 50× 5/18

= 13.8m/s

Answer 2

Answer:

here, distance is

                    150 km= 150000m

          time taken is

                         3 hrs= 3× 60×60

                                  = 10800 secs  

                      speed = distance / time

                                  = 150000/ 10800

                                  = 19.89 m/s      

                       SPEED = 19.98m/s
