That would really depend on the difficulty of the math problems. Some problems can be solved in seconds by somebody experienced in math, others may take hours.
There are two possible answers: 2/5 problems per minute or 5/2 minutes per problem. The logic behind these fractions is simple. You have two measures: 2 problems and 5 minutes. So one fraction, the first, is "2 problems" divided by "5 minutes" and the other is "5 minutes" divided by "2 problems".

The answer to the question, as worded, depends on out of how many minutes Jacob had 5/12 remaining. If you assume it was out of 1 minute, then Jacob was faster.
1 hour and 25 minutes = 85 minutes = 20 minutes @ 22 a minute + 20 minutes @ 15 a minute + 45 minutes @ 03 a minute = 440 + 300 + 135 = 875

this is a rate time problem. The long way to do this is:rate = (#problems completed)/(time) = (3/3) = 1so now we kow that three students complete 1 problem per minutethen one student completes 1/3 problem per minuteand 33 students complete 33*(1/3) problems per minute = or 11time = (# to complete)/(rate) = 33/11 = 3so it takes 33 students 3 minutes to coplete 33 problems.
Most people would run about a 6 minute mile to achieve a time of 18 minutes.
