Question

If Jessie can answer multiplication problems at a rate of 6 problems every 20 seconds. If she has a 10 minute test with 175 questions on it, will she finish in time?

Answer 1

yes

Explanation:

to solve this you must first find her rate

6 / 20 is her rate

you want to know how many she can do in ten minutes so we must find how many seconds are in 10 minutes

10 * 60 = 600

175 / 600 is the rate needed fro the test

now make them have the same denominator

6 / 20 is also 180 / 600

175/600 is less than 180/600 so yes she will finish the test in time
