Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. How far does Kristen travel to work

Answer: 19 miles

Step-by-step explanation:

Distance = speed * time

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. This means that the distance covered on her way to the train station is

0.5 * 10 = 5 miles

Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. Distance covered by the train is

0.5 * 28 = 14 miles

Therefore, the distance that Kristen travels to work is

14 + 5 = 19 miles

Answer: 38 mph
