Question

In lixue's garden, the green pepper grew 5 inches in 3/4 month. At this rate, how many feet can grow in one month? (Let 5 inches =5/12 feet)

Answer 1

`(5)/(9)`ft

Explanation:

Given parameters:

number of inches of growth = 5inches

time duration =
`(3)/(4)`month

Unknown:

Number of feet that can grow in one month = ?

Solution:

To find the rate;

Rate of growth =
`(number of inches of growth)/(time duration)`

Insert parameters and solve;

Rate of growth =
`(5)/((3)/(4) )`

Rate of growth = 5inches x
`(4)/(3)`

=
`(20)/(3)`inches/month

Now,

Number of feet in one month:

= rate of growth x 1 month

=
`(20)/(3)`inches/month x 1 month

=
`(20)/(3)`inches

Since; 5inches =
`(5)/(12)`feet

`(20)/(3)`inches will give
`((5)/(12) x (20)/(3) )/(5)` ft

=
`(5)/(9)`ft
