Question

A competition problem requires one hour to fully develop (write, proofread, edit, and typeset). This problem is then given to 30,000 students, each working an average of 24 seconds to solve the problem. What is the ratio of a problem's development time to the total time spent by the students to solve the problem?

Answer 1

1250

Explanation:

30,000/24

divide both sides by 24 to get 1250.

Answer 2

1/200

Explanation:

since you do 30000*24=720000 and you then divide it by 3600 to get 200 hours so it is 1/200
