Ben can complete 4 math problems in 20 minutes. If he continues working at the same rate, how long will it take Ben to complete 17 math problems?
20/4 = 5
He takes 5 minutes to complete each problem.
Can you take it from there?
20/4=5
5*17=85
Therefore it will take him 85 min to complete 17 questions.
To find out how long it will take Ben to complete 17 math problems, we need to first calculate the number of math problems Ben can complete per minute.
Since Ben can complete 4 math problems in 20 minutes, we can divide the total number of math problems by the total time it takes to get the rate per minute.
The rate per minute is calculated as:
4 math problems / 20 minutes = 0.2 math problems per minute
Now that we know Ben's rate per minute, we can calculate how long it will take him to complete 17 math problems.
To do this, we can divide the total number of math problems by the rate per minute:
17 math problems / 0.2 math problems per minute = 85 minutes
Therefore, it will take Ben 85 minutes to complete 17 math problems if he continues working at the same rate.
