Question

6. A car moves with a speed of 50 km/h
for 20 min and then with a speed of 60
km/h for the next 15 min. What is the
total distance covered by the car?​

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
