If a sprinkler waters 1/15 of a lawn in 1/3 hour, how much time will it take to water the entire lawn?
sammy [17]

Answer:

ok so first we know that 1/3 of a hour is 20 minutes since

60*1/3=20

so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15

20*15=300

300 minutes or 5 hours

Hope This Helps!!!
