Answer 2

Hey friend!

1 km = 1000 m

1 hour = 3600 sec

Distance travelled by the car in 1 hour (60 minutes) = 72 km

Distance travelled by the car in 1 second = 72 * 1000/3600

                                                                       = 72000/3600

                                                                       =20 m/s

Distance travelled in 1 second = 20 m  

Distance travelled in 30 seconds = 20*30

                                                         =600 m

So, the car travelled 600 metres in 30 seconds.
