Question

A car runs 60 km in 1 ½ hours. a) How much distance will it cover in 5 hours? b) How much time will it take to cover 75 km? ​

Answer 1

Answer:

Given:-

• Distance covered by car in 1*1/2 hours=60km.

Find:-

• How much distance will it cover in 5 hours?
• How much time will it take to cover 75 km?

Solution.

Distance covered by car in 1*1/2 hours or 90 minutes=60km /60000 m.

Distance covered by car in 1 minutes

=60000/90=667m.

Distance covered by car in 5 hours or 300 minutes=300×667=200100 m.

_________________________________________

60 km/60000m distance covered by car =1*1/2hrs or 90 minutes.

1m distance covered by car

=90/60000.

75km or 75000m distance covered by car

=9/6000*75000.

=112.5 or 113 minutes.

=1 hour 53 minutes.

Hope it will help you.
