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) 50 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.
