A car travelled at 100km/h for two hours, at 60km/h for the next two hours and finally at 80km/h for one hour. What is the car's average velocity for the entire journey?

Answer:

Speed=100km/h

time taken=2 hrs

speed 60km/h

time taken=2 hrs

speed=80km/h

time taken=1 hr

Average velocity =total distance/total time taken = 100+60+80 = 240 = 48km/h

2+2+1 5
