Derek applies grass seed to 2/5 acre in 3/4 hour. How many acres can Derek cover per hour?

Answers

The area that can be covered with grass seed by Derek is 8/15 acres.

Time spent while applying grass seed to 2/5 acre = 3/4 hour

Or, 3/4 hour is needed to apply grass seed to 2/5 acre.

What is a unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

3/4 hour ≡  2/5 acre

1-hour ≡ (2/5)/(3/4) acre

1-hour ≡ (2)/(5) *(4)/(3)

1-hour ≡ (8)/(15) acre

So, Derek can cover (8)/(15) acre per hour.

Hence, the area that can be covered with grass seed by Derek is 8/15 acres.

Sheryl has a basket of ripe apples and peaches. The number of apples in the basket is 12 more than twice the number of peaches. If there are 36 apples in the basket, there are peaches in the basket. NextReset

a = 2p + 12...and there are 36 apples (a)
36 = 2p + 12
36 - 12 = 2p
24 = 2p
24/2 = p
12 = p...so, if there are 36 apples (a), then there are 12 peaches (p)
