Answer to Question #173016 in Physics for Louis

Question

 Calculate the velocity of MV Lea that travels 48 nautical miles in 45 minutes.

a. 0.94 knot b. 1.11 knots c. 46 knots d. 64 knots

Answer 1

The velocity in knots can be found by dividing distance in nautical miles by time in hours. So, since 45 minutes represent 3/4 of an hour, the velocity is

$$v=\frac{48}{3/4}=64\text{ kn}.$$
