A man rows upstream 36 km and downstream 48 km taking 6 hours each time. The speed of the current is

0.5 km/hour

1 km/hour

2 km/hour

1.5 km/hr

Explanation:

Speed = Distance/time
Downstream Speed = x + y = 48/6 = 8 km/h
Upstream speed = x – y = 36/6 = 6 km/h
x + y = 8 km/h ……….. (i)
x – y = 6 km/h ………… (ii)
Solve equation (i) and (ii)
x = 7 km/h
y = 1 km/h.
Thus, Speed of the current is = 1 km/ hr.
