Distance travelled in first time = 90 km
Time taken in first time = 2.5 hours
Speed of car = Distance /Time
= 90 / 2.5
= 900 / 25
= 36 km/h
Distance travelled in second time = 30 km
Time = Distance /Speed
= 30 / 36
= 5/6 hours
Time taken = 5/6 hours
= 5*60 / 6 min
= 50 minutes
Time taken in first time = 2.5 hours
Speed of car = Distance /Time
= 90 / 2.5
= 900 / 25
= 36 km/h
Distance travelled in second time = 30 km
Time = Distance /Speed
= 30 / 36
= 5/6 hours
Time taken = 5/6 hours
= 5*60 / 6 min
= 50 minutes
