A car moves with

Answer :

Speed of the car in the first 15 minutes = 40 km/h


So, distance traveled in the first 15 minutes will be = speed x time


Distance = 40km/h x 15 minutes


Distance = (40 x 15/60) km = 10 km


Speed in next 15 minutes = 60 km/h


Distance traveled in next 15 min= speed in next 15 minutes × time


= 60 km/h x 15 min


= h


Distance in next 15 minutes = 15 km


The total distance covered by car = distance in first 15 min+ distance in next 15 min


Total distance = 10+15


= 25 km.
