Question

speed of a car is 108 km/h . how much distance it can cover in 15 seconds? briefly explain the answer.

Answer 1

108km/hr = 30m/s
distance in 15 sec = 15 x 30 = 450 m = 0.45km

Answer 2

Note: 1Km/hr = 5/18 m/s.


Given Speed of the car = 108km/hr.

                                        = 108 * 5/18

                                        = 30m/sec.


Therefore the distance covered in 15 seconds = 15 * 30

                                                                               = 450m.


Hope this helps!
