Samuel drove 28 miles in 32 minutes. Beverly drove 42 miles in 48 minutes.

Are the ratios of miles to minutes for Samuel and Beverly proportional?

28 miles in 32 minutes. We need to find how far in 1 minute, so 32 divided by 32 gives us 1 minute. 28 divided by 32 gives 0.875 miles in a minute.

Apply to Beverly. 48 divided by 48 to give 1 minute. 42 divided by 48 is 0.875 miles in a minute.

The answer is yes, they are proportional.
