Question

You have discovered a computer program that can solve algebra problems at a rate of 2 problems per second use this ratio to calculate how many problems the program can solve in one minute

Answer 1

Well lets set up an equation 2 problems per second yields
$2x$
for every second, x.
Now if we want the problems solved, y it will be equal to this product so
$y = 2x$
Now lets plug in 60 seconds, which is 1 minute
$y = 2(60) \\ y = 120$
It can solve 120 algebra problems in 1 minute.
