Answer:
min
Step-by-step explanation:
In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:
we can start solving this subtraction by turning all of the numbers into improper fractions so we get:
next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:
and now we can subtract the numerators and copy the denominators so we get:
which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:
min
and this is the amount of time he has available to solve the las problem.
