Answer:
BX
Step-by-step explanation:
D = RT is an extremely important and useful formula. This formula relates distance, to rate, and time.
In this question, we are asked to find the DISTANCE travelled in the biking portion of the triathlon. Looking back to the formula, we see that the distance is equal to the rate multiplied by the time.
The rate biking is also called the average speed, which is represented by an X in this problem.
The time biking is represented by a B in this problem.
Thus, we obtain our final answer, B times X, or simply written as BX.
