Question

car covers the first half of the distance between two places at a speed of 40 kilometre per hour to kilometre per hour the avg speed of the car is​

Answer 1

Answer:

40 km

Explanation:

suppose the total distance is 2X

half distance covered 40 km/hr so the time period(t1)taken by the half distance is X/40

also the half distance covered by 40 km/hr so the time taken(t2) by the half distance is X/40

total time period =t1+t2

X/40+X/40=2X/40

avg speed=total distance/total time taken

2X/2X/40=40kilometre
