R*T = D

50T + 30T = 200
80T = 200
T = 2.5

A. 11:30am

I did an approximation to come up with the answer.

Rob will have driven half the distance in two hours (50 mph * 2hrs = 100 miles).

David will be at 60 miles iun the same time.

After 3 hours - Rob would be at 150 and David will be at 120 miles which means they would have crossed.

Hence, only possible answer is A.

A

effective speed = 50+30=80

time taken = 200/80=2.5 hours

so 9+2.5 =11.30 am

Assuming that neither of the two cross a time zone the answer should be (A).

r*t=d

50+30t=200
80t=200
t=2.5

9+2.5=11.5 (or 11:30)
