Question

Biking at 8 mph, it takes Kristen hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another hour for her to get to work when the train travels 28 mph. How far does Kristen travel to work?

Answer 1

d = 18 mi

Explanation:

Write a distance equation, dist = speed * time

:

Total dist = bike dist + train dist

d = 12(.5) + 24(.5)

d = 6 + 12

d = 18 mi
