Q8 A group of ecologists collected data on the velocity of a river otter using a motion sensor. The motion sensor measured that the river otter was swimming at 3 meters per second. The ecologists are interested in finding out how many seconds it would take for the otter to swim 150 feet if it continues to swim at a constant speed of 3 meters per second. 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: feet
Option #2: seconds
Option #3: meters

I would need to convert the units of distance from meters to Option #

Answer 1

To solve the problem, you need to convert the distance the otter needs to swim (150 feet) into meters, so that you can use the velocity of 3 meters per second without dealing with different units.

1 meter is approximately equal to 3.281 feet. Therefore, you can convert feet to meters by using the ratio.

In this case, you should enter:

Option #3: meters

You would convert 150 feet into meters to match the velocity units.
