Javier solves three math problems in five minutes. He has 20 math skill-work questions for homework, and he wants to complete them before talking with friends. How many minutes will javier take to complete 20 math skill work questions
3/5 = 20/x
Cross multiply and solve for x.
3x = 100
x = 33.333 minutes
To find out how many minutes it will take Javier to complete 20 math skill work questions, we can use the information given. Javier solves three math problems in five minutes. This means he can solve 3/5 = 0.6 math problems per minute.
Now, let's calculate how many math problems Javier can solve in total. We know that he wants to complete 20 math skill work questions, so he needs to solve all of them.
To find out how many minutes it will take, we divide the total number of math problems by the number of math problems Javier can solve per minute. We can set up the equation:
Total time = Total math problems / Math problems per minute
Total time = 20 / 0.6
When we divide 20 by 0.6, we get 33.33. Since we are dealing with time, we round up the answer to the next whole number. Therefore, it will take approximately 34 minutes for Javier to complete 20 math skill work questions.
