Question 1 1 of 5
Two trains leave stations 50 miles apart at the same time heading toward one
another on parallel tracks. Train A is traveling 60 miles per hour, while Train B is
going 80 miles per hour. The dispatcher wonders how long it will take them to meet
each other.
Using the formula d=rt, where d is the distance traveled (in miles), r is the rate the
train is traveling (in miles per hour) and t is the time (in hours), identify a system of
equations you can use to solve this problem.
O Train A: d = 50 + 60t Train B: d = 80t
O Train A: 50 – d = 60t
Train B: d = 80t
O Train A: d = 60t - 50 Train B: 50 – d = 80t
o Train A: d = 801 Train B: d = 601
