Question

e. A car moves with a speed of 60 km/h for the first half an hour and with a speed of 45 km/h in the next
half an hour. What is the total distance covered by the car?​

Answer 1

a car moves with a speed of 60 km/h for the first half hour .

we know, distance = speed × time.

here, speed = 60km/h and time = 0.5hr

so, distance = 60 × 0.5 = 30km

again car moves with a speed of 45km/h in the next half an hour.

here speed = 45km/h and time = 0.5 hr

so, distance = 45 × 5 = 22.5 km

hence, total distance covered by the car = 30km + 22.5 km = 52.5 km
