1. convert 30 ft per s to mi per min.
5280 ft = 1 mi
2.a turtle swims at a speed of 12 mph. a boy swims at a speed of 4.4 ft per s.
3 ft = 1 yd
5280 ft = 1 mi
how much faster does the turtle swim than the boy in yards per minute?

In converting measurements, we use conversion factors to multiply to the given value. For the first item, the conversion factor would be 5280 ft = 1 mi and 1 min = 60 s. We calculate as follows:

30 ft / s ( 1 mi / 5280 ft ) ( 60 s / 1 min ) = 0.34 mi / min

For the second item, we calculate as follows:

Turtle's speed: 12 mi / hr ( 5280 ft / 1 mi ) ( 1 yd / 3 ft ) (1 hr / 60 min) = 352 yd / min

Boy's speed: 4.4 ft / s ( 1 yd / 3 ft ) ( 60 s / 1 min ) = 88 yd / min
