Question

Sean prepared 44 kilograms of dough after working 11 hours. How many hours did Sean work if he prepared 48 kilograms of dough? Assume the relationship is directly proportional.

Answer 1

This is an example of direct variation.

So, 44 48

11 x

For this, you have to use the formula, 44x = 48 × 11

= (48 × 11) ÷ 44 = 12

Hence, your answer is 12 hours
