Answer:
1 hour and 30 minutes
Explanation:
First you need to create an equation in this case its 4+3x=1+5x
which is basically town 1 = town 2
then subtract 3x from both sides leaving you with the equation 4=1+2x
then subtract 1 and you end up with 3=2x divide by 2 and you get 1.5=x which is 1 hour and 30 minutes
