Question

If a sprinkler waters 1 over 8 of a lawn in 1 over 2 hour, how much time will it take to water the entire lawn

Answer 1

If a sprinkler waters 1/8 of a lawn in 1/2 hour, then it can water 1/8 of the lawn in 1 hour. Therefore, it would take 8 times as long (8 hours) for the sprinkler to water the entire lawn.
