Question 533546
The cars are moving in opposite directions so they are getting farther and farther apart at their combined speed:  50+60 mph = 110 mph.
.
At 110 mph how long does it take to go 330 miles?
.
330 miles/110 mile/hr = 3 hr
.
The question as "at what time" will they be 330 miles apart.

10 a.m + 3 hr = 1 p.m.
