You can put this solution on YOUR website! a)
b)Sally rides 21t. Teresa rides 15t
c) The two distances adds up to 60.
21t+15t=60
36t=60
6t=10
t=10/6
t=5/3= 1 2/3 hours =1 hr and 40 minutes
d) Depends. Does the park have any facilities? How safe is the park? Are there roads to the park? Pretty dumb question.
