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?

Respuesta :

the turtle swims at a speed of 21,120 yards per minute (12 x 5280 = 63,360, 63,360/3 = 21,120) and the boy swims at a speed of 88 yards per minute. So the turtle swims 21,032 yards per minute faster than the boy.
12 / 60 minutes = 0.2 miles per minute
0.2 × 5280 ft = 1056 ft per minute
1056 ÷ 3 ft = 352 yds per minute

4.4 x 60 = 264 ft per minute
264 ÷ 3 = 88 yds per minute

352 - 88 = 264 yds per minute faster
