Dori and Malory are tracking their steps taken as a health goal. Dori leaves her house at 12:00 p.m. and walks at 50 steps per minute. Malory leaves her house at 12:20 p.m. and walks at 90 steps per minute.
At what time will Malory's steps catch up to Dori's steps?

Henry
50steps/min * 20min = 1000 Step headstart for Dori.
90 * T = 50 * T + 1000.
90T = 50T + 1000
T = 25 min. to catch up.
