A man's speed with the current is 15 km / hr and the speed of the current is 2.5 km/ hr. The man's speed against the current is: 8. 5\ k m//h r b. \ 9\ k m//h r c. 10\ k m//h r d. 12. k m//h r

The speed of boat in downstream is 15 km/hr and the speed of the current is 2.5 km/hr. The speed of boat against the current is:

Speed of a speed-boat when moving in the direction parallel to the direction of the current is 16 km/hr. Speed of the current is 3 km/hr. So the speed of the boat against the current will be (in km/hr)

Quantity I: If the speed of the boat in the direction of current is 13 km/hr and the speed of the current is 4 km/hr. What is the speed of the boat against current. Quantity: II The downstream speed and upstream speed of the boat is 13 km/hr and 3 km/hr respectively. What is the speed of the stream

A man rows at the rate of 5 kmph in still water and his rate against the current is 3.5 kmph, then the man's rate along the current is:
