Tirupati travels 120 km at the speed of 48 km/hr and another 180 km at the speed 45 km/hr. What is Tirupati’s average speed (in km/hr) during the entire journey? (correct up to two decimal places)

Correct option is A

Given:
Distance ₁ = 120 km
Speed ₁ = 48 km/hr
Distance ₂ = 180 km
Speed ₂ = 45 km/hr
Formula Used:
Total time = Distance ÷ Speed
Average speed = Total distance ÷ Total time
Solution:
Time for Distance₁ = 120 ÷ 48 = 2.5 hours
Time for Distance₂ = 180 ÷ 45 = 4 hours
Total time = 2.5 + 4 = 6.5 hours
Total distance = 120 + 180 = 300 km
Average speed = $$\frac{300}{ 6.5}$$​ = 46.15 km/hr
