Train Trekker

Ahn rode trains during rush hour, when many people hurry to and from work. That’s when trains are the most frequent.

Let’s say the morning rush is from 7 a.m. to 9:30 a.m., and the evening rush is from 4 p.m. to 7 p.m. What is the elapsed time between the beginning of the morning rush to the end of the evening rush? Draw and fill in a number line on a separate sheet of paper.

Sometimes it was faster for Ahn to run on the street between stations than it was to ride the train.

This happened in the Bronx. Ahn exited the 241st Street stop at 12:34 p.m. He ran 1.9 miles and arrived at Dyre Avenue 18 minutes later. Draw his arrival time at Dyre Avenue on an analog clock face.

The A is the longest train line—more than 31 miles!

Let’s say the train’s average speed is 25 miles per hour. Could you visit all the stops on the A train in 1 hour? Explain why or why not.

Ahn’s 2016 record was 21 hours, 28 minutes, and 14 seconds.
