By travelling at speed of 60km/hr, the car takes 2hrs to reach his destination, i.e. he travels 60*2 = 120km.

By travelling at speed of 80km/hr, he will take 120/80 = 1.5 hr or 1 hour and 30 minutes to reach his destination.

Answer 2

time -2 hour
speed-60 km/hr
distance-speed *time
2*60=120 kms
when speed 80 km/hr
so time=distance/speed
120/1.5 hr=1 hour and 30 minutes
