Quantitative Aptitude (SBI-CL) Boats and Streams

Speed of a boat in still water is 22 km/hr and speed of stream is 3 km/hr. Find the sum of the distances travelled by boat in 1 hour 24 minutes in downstream and 2 hours in upstream.

73 km

68 km

58 km

78 km

None of these

Explanation:

Downstream speed= 22+3= 25 km/hr
Upstream speed= 22-3= 19 km/hr
Distance travel by Boat in Downstream in 1 hour 24 minutes = 25×7/5= 35 km
Distance travel by Boat in Upstream in 2 hour = 19×2= 38 km
Required Sum of distances = 35+38= 73 km
