Question

How long will this trip take? A bike 15 miles per hour on a biking trail to a trailhead 30 miles away.

Answer 1

2 hours

Explanation:

Distance = Rate * Time

If we replace these with the numbers in the problem and use "t" as the variable, it becomes:

30 miles = 15 mph * t

Now, to solve:

30 = 15t

divide both sides by 15

t = 2

add the units

time = 2 hours
