# A car moves with

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.
