Answer: 1.5 hours
Step-by-step explanation:
If Thiago and Brandon move in opposite directions at speeds of 80mph and 70mph then after 1 hour Thiago will have traveled 80 miles and Brandon will have traveled 70 miles.

Then we know that after t hours have elapsed they are 225 miles
Then we pose the following equation
Now we solve for t
