Question

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. The total distance covered by the car is​

Answer 1

Answer:

25km

Step-by-step explanation:

For first half of distance:

car's speed = 40km/h

Time = 15 minutes = 15/60 = 1/4 hrs

distance travelled = speed*time = 40*1/4 km = 10km

For second half of distance:

car's speed = 60km/h

Time = 15 mins = 15/60 = 1/4 hrs

Distance = speed*time = 60*1/4 = 15km

Total distance = (15+10)km = 25km

25km is the total distance covered by the car
