A car covers a distance of 48 km at a speed of 40 km/h and another 52 km with a speed of 65 km/h. What is the average speed of the car (in km/h) for the total distance covered ?

52.5 50 52 33

Distance = Speed × Time Time  = \(\frac{DIstance}{Speed}\)  Time 1 = \(\frac{48}{40}\)  = 1.2 hours Time 2 = \(\frac{52}{65}\) = 0.8 hours Average Speed = \(\frac{100}{2}\)  = 50 km/h \(\frac{54}{100}\)
