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.
