Question

Joe swam at the rate of 4.5 miles per hour. Joseph swam at the rate of 1/12 of a mile per minute. Who was swimming faster? By how many miles per hour faster?

Answer 1

Joseph was swimming faster because 1/12 of a mile per minute is around 5 miles per hour so Joseph was swimming 0.5 miles per hour faster than Joe.

Answer 2

It is given Joe swam at the rate of 4.5 miles per hour. Joseph swam at the rate of
`(1)/(12)` of a mile per minute.

Joseph swam
`(1)/(12)` mile in one minute .

60 minutes = 1 hour.

Number of miles Joseph swam in 1 hour=
`(1)/(12) times 60= 5` miles

Joseph swam 5 miles in one hour .Or Joseph swam at the rate of 5 miles per hour.

Joseph was swimming faster then Joe by 5-4.5 = 0.5 miles per hour.
