Question

A scuba diver is returning to the surface from a depth of 165 feet. The safe ascent rate for a diver is 30 feet per minute. How many minutes will it take the diver to return to the surface?

Answer 1

5 1/2 minutes.

165 feet total distance divided by 30 feet per minute.

That leaves you with 5 minutes (150 feet), plus a remainder of 15 feet, which is half of what can be done in a minute.

Ergo, 5 1/2.

Answer 2

Its just 165 divided by 30, since the diver travels 30 feet evey minute.

Answer 3

165ft/ 30ft/min

cross off the feet and you are left with 5.5 minutes

Answer 4

165/30 = 5.5mins
