Question

Ms. Reynold's sprinkler system has 3 stations that water all parts of her front and back lawn. Each station runs for an equal amount of time. If it takes 14 minutes for the first 2 stations to water, how long does it take to water all parts of her lawn?

Answer 1

21 minutes

Sprinkler has 3 stations

Each waters for an equal amount of time ;

First 2 stations water for 14 minutes

Time taken per station * number of stations

7 minutes * 3 = 21 minutes
