Question

calculate the speed of a moving car in m/sec which travels 120km in 2 hours

Answer 1

Answer:

given:

distance=  120 km

time= 2 hours

first convert km to m.

1km = 1000m

120km = 1000 x 120

           = 1,20,000

now convert hours to seconds.

1 hr = 60 min

1min = 60 sec

∴ 1hr = 60 x 60 sec.

                      = 3600 sec

2 hr = 3600 x 2

       = 7200 sec

now, to find speed:

formula: speed = distance ÷ time.

∴ speed = 1,20,000 ÷ 7200

                            =  16.6666666667 m/sec
