Answer:

Yes

Step-by-step explanation:

To tell if 84 feet in 12 seconds is equivalent to 217 feet in 31 seconds, first put them in equation form.

84 feet in 12 seconds as an equation is 84ft/12sec or 84/12.

This can be simplified to 7ft/1sec so the rate of travel is 7 feet per 1 second.

217 feet in 31 seconds as an equation is 217ft/31sec or 217/31.

This can be simplified to 7ft/1sec

7/1 is the same rate as the first equation therefore 4 feet in 12 seconds is equivalent to 217 feet in 31 seconds.
