1-55.

A marathon runner runs a 26.2-mile race. Her distance traveled in miles after *t *hours is *p*(*t*) = 7*t*. Homework Help ✎

How long does it take her to finish the race?

26.2 =

*p*(*t*)

Solve for*t*.What is her average velocity? Explain your reasoning.

Evaluate and explain.

Suppose she runs at a constant pace of 7 miles/hour. How far will she have gone in 2 hours?

Evaluate.

Show how the units in your answer to part (c) reduce using (rate)(time) = distance.

(rate)(time)= (miles/hour) (hours) = _________
