Hi swerve,
We're asked for how long it took Jason to drive nonstop from his home to Glendale. This question is based on the Distance Formula (Distance = Rate x Time)
(1) Glendale is 400 miles from Jason's home.
Fact 1 gives us the distance, but we still need Jason's rate to determine the time it took him to travel that distance.
Fact 1 is INSUFFICIENT
2) Jason's average speed for the trip was 50 miles per hour.
Fact 2 gives us the rate, but we still need Jason's distance to determine the time it took him to travel that distance.
Fact 2 is INSUFFICIENT
Combined, we know the distance (400 miles) and the rate (50 miles/hour), so we can figure out the time to travel that distance (in this case, 8 hours)
Combined, SUFFICIENT
Final Answer: C
