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?

4/7 of an acre per hour

4/7 acre

To find out how many acres Walter will mow in an hour, we need to determine the amount of lawn he can mow in one hour.

Given that Walter takes 7/10 of an hour to mow 2/5 of an acre, we can set up a proportion to find the number of acres he can mow in 1 hour.

Let's represent the number of acres mowed in 1 hour as x.

The proportion can be set up as follows:

(7/10) hour = (2/5) acre
x acres 1 hour

To solve for x, we can cross-multiply:

(7/10) * 1 hour = (2/5) * x acres

7/10 = (2/5) * x

To isolate x, we can multiply both sides of the equation by 10/2:

(7/10) * (10/2) = (2/5) * (10/2) * x

7/2 = (20/10) * x

7/2 = 2 * x

To solve for x, we can multiply both sides of the equation by 2/2:

(7/2)*(2/2) = 2 * x * (2/2)

7/2 = 4 * x/2

7/2 = 2 * x

Now, we can simplify the equation:

7/2 = 2 * x

Divide both sides of the equation by 2:

(7/2)/2 = x

x = 7/4

Therefore, Walter will mow 7/4 of an acre in one hour.

thanks but id wont work

Lakaiwkwkwkk Select the correct answer.

Walter takes of an hour to mow of an acre of lawn. At this rate, how many acres will he mow in an hour?

ttttttttttttthhhhhhhhhhhhhhhhhhhhhaaaaaaaaaaaaaaannnnnnnnnnnnnnnnnnnnnnnkkkkkkkkkkkkkkkkkkkkkyyyyyyyyyyyyyyyyyyyyyooooooooooooooooooooooooouuuuuuuuuuuuuuuuuuuu

ooooooootttaaayyyy

7/10 of an hour to mow 2/5 of an acre.

This means in 42 minutes he mowed 2/5 of an acre because 7/10 * 60minutes = 42 minutes

This implies that he mows 1/5 of an acre in 21 minutes.
