Question

the number of hours h that it takes for ice to malt varies inversely with the temperature t it takes 3hours for a piece of ice to melt at 45°c fine (a) the constant of variation (b) the equation for this situation in the form h=k÷t (c) the value of t if h=4 hours​

Answer 1

Answer:

Step-by-step explanation:

Formula

h = k/temp

Givens

h = 4 hours

t = 45 degrees

Solution

3 = k / 45                  Multiply both sides by 45

3*45 = k

k = 135

Problem

what happens when h = 4 hours?

h = 4

k = 135

temp = ?

4 = 135 / temp       Multiply both sides by temp

4temp = 135          Divide by 4

temp = 135 / 4

temp = 33.75

Note that as the time went up, the temperature came down
