Question

The time allotted to complete a math quiz and a word puzzle is 25 minutes. The time allotted to complete 2 math quizzes and a word puzzle is 40 minutes. What is the time allotted to complete a math quiz?

Answer 1

Answer:

Time alloted for Math Quiz=10 mins

Step-by-step explanation:

Let the time allotted to solve math quiz be x hours and the time allotted to solve word puzzle be y hours.

According to the question,

x+y=25/60

=>x+y=5/6

And,

2x+y=40/60

=>2x+y=2/3

By eliminating y from both the equations,

x=5/6-2/3=1/6 hrs=10 mins
