Solution
Average speed = Total distance / Total time taken
Total distance = 35 + 69 = 104 km
Total time = 45 + 75 = 120 min = 2 hr
Average speed = $\frac{104}{2} = 52~km/hr$
Average speed = Total distance / Total time taken
Total distance = 35 + 69 = 104 km
Total time = 45 + 75 = 120 min = 2 hr
Average speed = $\frac{104}{2} = 52~km/hr$
