Question

A car moves with a speed of 40 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:

taking speed 1=40km/hr

time 1=20min

distance1=speed1/time1

putting the values

distance1=40/20=2km

taking speed 2=60km/hr

time 2=15 min

distance 2=speed2/time2

putting values

distance 2=60/15=4km

total distance =distance 1+distance 2

=2+4=6km
