Problem: A bus travels 2/5 of a total journey at its usual speed. The remaining distance was covered by the bus at 6/7 of its usual speed. Due to slow speed, it reaches its destination 50 minutes late. If the total distance is 200 km, then what is the usual speed (in km/hr) of the bus?

Solution:

Let the usual speed of the bus be x km/hr.

Given, the total distance = 200 km

Let the distance covered at usual speed be 2/5 of 200 km = 80 km

Remaining distance = 200 - 80 = 120 km

Time taken to cover 80 km at usual speed = distance/speed = 80/x hours

Time taken to cover 120 km at 6/7 of usual speed = distance/speed = 120/(6x/7) = 140/x hours

Total time taken = 80/x + 140/x + 50/60 hours = (480 + 840 + 50x)/(60x) hours

According to the problem, the bus reaches the destination 50 minutes late, i.e., (50/60) hours late.

Therefore, the total time taken should be (200/x) hours + (50/60) hours.

Equating both the expressions, we get

(480 + 840 + 50x)/(60x) = (200/x) + (50/60)

Simplifying the above equation, we get

x = 24 km/hr

Therefore, the usual speed of the bus is 24 km/hr.

Answer: The usual speed (in km/hr) of the bus is 24 (option B).
