(1 3/4) / (3/4) = x / 1.....1 3/4 miles to 3/4 hrs = x miles to 1 hr
cross multiply
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = 7/4 * 4/3
x = 28/12
x = 2 1/3 miles in 1 hr <==
Plant's height after 31 months:82 centimeters
<h3>How to find the height of the plant</h3>
The equation that can be used to find the height of the plant is given as
h = 52 centimeters + 1m
We have that the plant grows at 1 centimeter every month hence we have 1m in the equation.
Then the number of periods is m, Now we are to find the height in this period of time
h = 52 + 1*31
= 51 + 31
= 82
Hence the height after 31 months is given as 82 centimeters.
