Therefore, the first 60 miles took Brian 1.875 + 2 = 3.875 hours to complete. After resting for an hour,
he’s used up 4.875 of his 8 hours, so he has 3.125 hours left. He needs to go 40 miles in that time, so draw
one more pie with 40 at the top and 3.125 in the lower right for time. Divide 40 by 3.125 to get 12.8 or 13
miles per hour (it is okay to round, since you are looking for the approximate speed).
The correct answer is (C).
PROBABILITY
Probability is a mathematical expression of the likelihood of an event. The basis of probability is simple.
The likelihood of any event is discussed in terms of all of the possible outcomes. To express the
probability of a given event, x, you would count the number of possible outcomes, count the number of
outcomes that give you what you want, and arrange them in a fraction, like this:
