Question

a car travels along a straight line for first half time with a speed of 40 km/h and the second half time with a speed of 60km/h . Find the average speed of the car​

Answer 1

Explanation:

Average speed Formula = 2*s1*s2 / (s1+s2)

here, s1 = speed of first half, and s2 = speed aif second half

given, s1 = 40

s2 = 60

Average speed = 2*40*60 / (40+60)

= 2*40*60 / 100

= 48 km/hr
