Question: A car travels 200 km in 4 hours and then 300 km in 6 hours. What is the average speed of the car for the entire journey?
a) 60 km/h
b) 65 km/h
c) 70 km/h
d) 75 km/h
Solution:
Total distance covered:
Total distance=200+300=500 km
Total time taken:
Total time=4+6=10 hours
Average speed:
Average speed=500⁄10 =50 km/h
Hence, the average speed for the entire journey is 50 km/h.
