A man completes 30 km of a journey at 6 km/h and the remaining 40 km of the journey in 5 h. Find the average speed for the whole journey.

A) \( \Large 6 \frac{4}{11} \) km/h
B) 7 km/h
C) \( \Large 7 \frac{1}{2} \)km/h
D) 8 km/h

Correct Answer:


B) 7 km/h

Description for Correct answer:
Total distance = 30 + 40 = 70 km

Total time taken = \( \Large \frac{30}{6}+5=\frac{60}{6} = 10 h \)

Therefore, Required average speed = \( \Large \frac{70}{10} = 7 km/h \)
