Question

A man can swim at 7.0 m/s. If the current is going against him at 3.7 m/s, what is his speed with respect to the bank?

3.3 m/s

10.7 m/s

7.0 m/s

3.7 m/s

Answer 1

The speed of the man with respect to the bank is the difference between his swimming speed and the speed of the current. Given that he can swim at 7.0 m/s and the current is going against him at 3.7 m/s:

Speed with respect to the bank = Swimming Speed - Speed of Current
Speed with respect to the bank = 7.0 m/s - 3.7 m/s = 3.3 m/s

So, the correct answer is:

3.3 m/s
