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.
hours
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.
