Solve the word problem.
The formula [tex]t = \frac{d}{r}[/tex] gives the time [tex]t[/tex] for a distance [tex]d[/tex] traveled at a rate [tex]r[/tex]. A train traveled 225 miles at a rate of 45 mi/hr.
How long did it take the train to travel this far?
A. 4.5 hr
B. 5 hr
C. 5.5 hr
D. 6 hr
Answer (2)
If you know the covered distance, and average speed, the only thin you have to do is to divide covered distance by average speed. 225/45 = 5 It will take 5h to cover this distance by this train with average speed 45 hi mi
The train took 5 hours to travel 225 miles at a speed of 45 miles per hour, using the formula t = r d . Thus, the correct answer is B. 5 hr.
