Q7 A group of marine biologists collected data on the velocity of a dolphin using a GPS tracker. The GPS tracker measured that the dolphin was swimming at 25 knots. The biologists are interested in finding out how many hours it would take for the dolphin to swim 45 nautical miles if it continues to swim at a constant speed of 25 knots. In order to use units to verify your rearrangement of the formula, what process needs to be done? Enter the value that corresponds to your answer.

Question

Option #1: miles
Option #2: nautical miles
Option #3: hours

I would need to convert the units of distance from knots to Option

Answer 1

To determine how many hours it would take for the dolphin to swim 45 nautical miles at a speed of 25 knots, you need to understand the relationship between speed, distance, and time.

The formula you can use is:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

In this case, you have:

• Distance = 45 nautical miles
• Speed = 25 knots

Since the speed is measured in knots (nautical miles per hour), you don't need to convert the units of distance from knots to anything else for the calculation.

Therefore, the correct answer to fill in the blank about what you need to convert the units of distance from knots to is:

Option #2: nautical miles

Thus, you would use the formula directly, as both distance and speed are already in compatible units (nautical miles).
