Two friends are 60 miles apart. They ride their bicycles to meet each other. Sally starts from the college and heads east riding at a rate of 21 miles per hour. At the same time, Teresa starts from the river and heads west, riding at a rate of 15 miles per hour.
a: How far does each cyclist ride in t hours?
Sally rides 21t miles
Teresa rides 15t miles
-----------------------
b: When the two cyclists meet, what must be true about the distances they have ridden? Write and solve an equation to find when they meet
EQUATION: 21t + 15t = 60
36t = 60
t = 5/3 hrs.
They both drove for 5/3 hours.
