Andrew and Richard are training for a bike race. Andrew starts cycling a course at 6:00
a. m. and rides at a steady pace of 12 miles per hour. Richard cycles the same course
at 7:00 a. m. and travels at a steady pace of 16 miles per hour.
Write and solve an equation to determine the number of hours after Andrew starts that
Richard will catch up to Andrew. Add this to Andrew's start time to determine the time
they will meet.
