- The speed of a boat in still water in 22 km/hr and the rate of current is 4 km/hr.
Question 1:
The speed of a boat in still water in 22 km/hr and the rate of current is 4 km/hr.The distance travelled downstream in 24 minutes is:
A. 9.4 km
B. 10.2 km
C. 10.4 km
Feedback Speed downstream = (22 + 4) = 26 kmph
Time = 24 minutes =24/60 hour = 2/5 hour
Distance travelled = Time × speed=2/5×26 = 10.4 km
Time = 24 minutes =24/60 hour = 2/5 hour
Distance travelled = Time × speed=2/5×26 = 10.4 km
D. 9.2 km
