Question

A car travels at 180.0 km/h for 2.8 hours, at 65.0 km/h for the next 3.5 hours, and finally at 100.0 km/h for 2.0 hours. What is the car's average velocity for the entire journey?

Answer 1

v = ~122.23 m/s

Explanation:

180(2.8) + 65(3.5) + 200 = 931.5

931.5/(2.8 + 3.5 + 2) = 122.2289 ≈ 122.23 = va
