Let the number of tests graded be g = 27
time taken t = 3 hours
Required
The constant relating the time and the number of tests
Step two:
<em>"The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another."</em>
so that the direct variation is
g∝kt
g=t/k
k= g/t
k=27/3
k=9
