Answer: (1) 55 km/h
Explanation:-
Let be the average speed of Menon = X km/h
Total distance = 600 km
The average speed of Joshua = 65 km/ h
Formula – 
Average speed = Total distance / total speed
According to the question,
600/(65 + X) = 5
600 = 325 + 5X
5X = 600 – 325
5X = 275
X = 275/5
X = 55 km/h
Hence, the answer is (1) 55 km/h.
