Respuesta :
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.
It is given Joe swam at the rate of 4.5 miles per hour. Joseph swam at the rate of[tex] \frac{1}{12} [/tex] of a mile per minute.
Joseph swam [tex] \frac{1}{12} [/tex] mile in one minute .
60 minutes = 1 hour.
Number of miles Joseph swam in 1 hour=[tex] \frac{1}{12} times 60= 5 [/tex] 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.
