Q3 Consider the formula that relates distance, velocity, and time (d = vt). If you are interested in the time it takes for a mouse traveling at a speed of 5 feet per minute to run across a 30-yard field, which unit conversion makes the most sense to use?

Question

Converting yards to feet by dividing 30 yards by 3 feet.
Converting yards to feet by multiplying 30 yards by 3.
Converting yards to feet by multiplying 30 yards by 1 yard/3 feet
Converting yards to feet by multiplying 30 yards by 3 feet/1 yard

Answer 1

To convert the distance of 30 yards into feet, you should use the correct conversion factor that involves yards and feet.

1 yard is equal to 3 feet, so to convert from yards to feet, you would need to multiply the number of yards by the number of feet per yard. Therefore, the correct conversion would be:

Converting yards to feet by multiplying 30 yards by 3 feet/1 yard.

Thus, the correct option is:

Converting yards to feet by multiplying 30 yards by 3 feet/1 yard.

This correctly gives you the distance in feet, which you can then use in the formula \(d = vt\).
