Question

Janice can mow 1/2 of a lawn in 3/4 of an hour. How long will it take her to mow a
whole lawn?

Answer 1

Should be 6/8 of 2hrs I think

Answer 2

1.5 hours

Explanation:

At the same rate, it will take her 3/4 hour to mow the other 1/2 of the lawn. Her total time will be 3/4 +3/4 = 3/2 hours, or 1.5 hours for the whole lawn.
