Question 505878
Use the variables as they suggested,
When he catches his mom they will both have traveled the same distance
write a distance equation; dist = speed * time
:
your dist = Mom's dist
65t = 55(t+1)
65t = 55t + 55
65t - 55t = 55
10t = 55
t = 5.5 hrs

Confirm this by finding the distances, they should be equal
65(5.5) = 357.5
55(6.5) = 357.5
