Question

A car moves at a speed of 20 km/h for 15 minutes and then at a speed of 60 km/h for next 15 minute. Calculate the total distance covered by the car. (5+15=20km)

Answer 1

Answer:

speed = 20km/h

time = 15mins = 1/4hr

distance1 = d1= speed×time = 20 × 1/4 = 5km

speed= 60km/h

time = 15mins = 1/4hr

distance2 = d2= speed×time = 60 × 1/4 = 15km

total distance = d1 + d2 = 5km + 15km= 20km

hope this helps.

Answer 2

Hi there!

Your Answer :-

1st Car :-

Speed = 20km/h

Time = 15 min = 1/4hours

Distance = S × T = 20 × 1/4 = 5 km.

2nd Car :-

Speed = 60km/h

Time = 15 min = 1/4hours

Distance = S × T = 60 × 1/4 = 15 km.

Total Distance :-

5 + 15 = 20 km.
