A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second.
3 ft = 1 yd
5280 ft = 1 mi
How much faster does the fish swim than the boy in yards per minute?
A taxi service offers a ride with an $5 surcharge and charges $0.50 per mile.

1a. 0.5x + 5 =< 30.
b. 0.5x =< 30-5
X =< 50 miles.
2. 12mi/h * 5280ft/mi * 1yd/3ft * 1h/60min = 352 Yds./min. = Speed of the fish.
4.4ft/s * 1yd/3ft * 60s/min = 88 yds./min. = Speed of the boy.
352 - 88 = 264 yds./min faster.
b. 0.5x =< 30-5
X =< 50 miles.
2. 12mi/h * 5280ft/mi * 1yd/3ft * 1h/60min = 352 Yds./min. = Speed of the fish.
4.4ft/s * 1yd/3ft * 60s/min = 88 yds./min. = Speed of the boy.
352 - 88 = 264 yds./min faster.

The equation would be 5+0.50x>= 30
X >= 50
X >= 50
