Question

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?

Answer 1

Yes. Ratios of miles to minutes for Samuel and Beverly are proportional

Explanation:

Samuel's speed can be calculated as following:

`28/32=0,875`

0,875 miles per minute.

On the other hand Beverly's speed can be calculated as following:

`42/48=0,875`

0,875 miles per minute

If we convert the speed to mile per hour:

`0,875*60=52,5`

It can be easily seen that both Samuel and Beverly drove at the same speed at 52,5 miles per hour.

Answer 2

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.
