Speed of wave = frequency x wavelength
= 250 x 6 = 1500 m/s.
The distance that the canoe moves in this process is 1.29 meters.
We first have to find the center of mass

Where
Ms = Woman's mass = 45
Mc = Canoe's mass = 60kg
Xs = position from left= 1 cm
Xc = position from left end of canoe's mass = 2.5cm
When we put these values into the equation we have:

The center of gravity lies at the center of this boat. Therefore,

5.00 - 1. 00 = 4 meters

To get the distance that is moved by this canoe
distance = 3.143-1.857
= 1.286
≈ 1.29 meters
The distance that the canoe moves in this process is 1.29 meters.

Answer:
3m/s
Explanation:
Time=5s
Distance =15m
Speed=distance/time
Putting the values
Speed=15m/5s
Speed=3m/s is the answer
