Question

Walter takes 7 10 of an hour to mow 2 5 of an acre of lawn. at this rate, how many acres will he mow in an hour?

Answer 1

Walter will mow 34 2/7 acres in an hour.

Step-by-step explanation:

To find out how many acres Walter will mow in an hour, we need to determine the fraction of an acre he mows in one minute and then multiply it by 60 to get the amount for one hour.

Walter takes 7/10 of an hour to mow 2/5 of an acre, so in one minute he would mow (2/5) / (7/10) = (2/5) * (10/7) = 4/7 of an acre.

Now, to find out how many acres he will mow in an hour, we multiply the acres mowed in one minute (4/7) by 60. So, Walter will mow (4/7) * 60 = 240/7 = 34 2/7 acres in an hour.
