Question

The circumference of a wheel is 3 in and is rotating 5 times a minute. How much of a distance will it have traveled in one minute?

Answer 1

3 inches if for 1 rotation.

So if it is done 5 times, the rotation will be 5 times.

Hence: 3* 5

Answer 2

Wait so I multiply 3 x 5?

Answer 3

Yes.

Answer 4

Answer 5

Don't forget the units, inches.

Answer 6

i AM STILL CONFUSED.....

Answer 7

how?

Answer 8

I DO NOT KNOW HOW MUCH IT WILL TRAVEL IN 1 MINUTE....

Answer 9

The wheel is rotating 5 times a minute, right? Each rotation of the wheel moves the circumference (3 inches) along the path. Distance traveled in 1 minute = 5 rotations/minute * 3 inches/rotation * 1 minute = 15 inches

Notice how the units cancel out leaving you the distance unit and nothing else. This is a valuable check to make sure you have done your conversions and setup correctly. If you end up with something like rotations * rotations/inches, you've done it wrong.
