Question

A car moves with a speed of 40km /h for 15 minutes and then with a speed of 60km/h for the next 15 minutes. Find the total distance covered by the car in this 30 minutes​

Answer 1

Answer:

PART - 1

Car's speed = 40 km/h

Time = 15 mins. = 0.25 hrs.

Distance = Speed × Time = (40 × 0.25) km = 10 km.

PART - 2

Car's speed = 60 km/h.

Time = 15 mins. = 0.25 hrs.

Distance = Speed × Time = (60 × 0.25) km = 15 km.

So, Total distance travelled = (10+15) km = 25 km
