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

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