Question

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second.

Answer 1

The Boy: 4.4 x 60 = 264ft per minute.  264 / 3 = 88yrds Per minute

The Fish: 12 x 5280 = 63360ft hr. 5280 / 60 = 1056ft minute 1056 / 3 = 352yrds

352 - 88 = 44 yards quicker then the boy.

44 x 3 = 132 feet quicker then the boy.

Answer 2

Answer:

The fish swims at a speed 264 yard per minute more than boy.

Step-by-step explanation:

A fish swims at a speed of 12 miles per hour

Speed of fish = 12 miles per hour

Given that

            3 ft = 1 yd

            5280 ft = 1 mi

             So 1 mile = 5280 ft = 1760 x 3 ft = 1760 yd

             1 hour = 60 minutes

Substituting

     $\texttt{Speed of fish = }12 mph=\frac{12\times 1760}{60}=352yd/min$

Speed of fish = 352 yard per minute.

A boy swims at a speed of 4.4 feet per second.

Speed of boy = 4.4 ft/s

$\texttt{Speed of boy = }4.4ft/s=\frac{4.4\times 60}{3}=88yd/min$

Speed difference = 352 - 88 = 264 yard per minute.

The fish swims at a speed 264 yard per minute more than boy.
