Detailed Solution

A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes.

Calculate the distance covered at 40 km/h:

Speed = 40 km/h
Time = 15 minutes = 15/60 hours = 0.25 hours
Distance = Speed × Time = 40 km/h × 0.25 hours = 10 km

Calculate the distance covered at 60 km/h:

Speed = 60 km/h
Time = 15 minutes = 15/60 hours = 0.25 hours
Distance = Speed × Time = 60 km/h × 0.25 hours = 15 km
Total distance covered:

Distance covered at 40 km/h = 10 km
Distance covered at 60 km/h = 15 km
Total Distance = 10 km + 15 km = 25 km
