Hanson prepared 36 kilograms of dough after working 4 hours. How many hours did Hanson work if he prepared 99 kilograms of dough? Assume the relationship is directly proportional.

Question

hours

Answer 1

To solve this problem using direct proportion, we can set up a proportion by comparing the amount of dough prepared with the hours worked:

36 kilograms / 4 hours = 99 kilograms / x hours

Cross multiplying, we get:

36x = 4 * 99

36x = 396

Dividing both sides by 36, we find:

x = 11

Therefore, Hanson worked for 11 hours.
