7 = 300/60 + 200/x
7 - 5 = 200/x

x= 100

Initial distance = 300 miles
initial speed = 60 m/hr
initial time = d/s = 5 hrs
Total time = 7 hrs, remaining time = total time of 7hrs - initial time of 5 hrs = 2 hours
Remaining distance = 200 miles
Speed for remaining distance = remaining distance / remaining time = 200 / 2 = 100 miles / hr

Total time = t1 + t2
7hrs = (300/60) + t2
t2= 2 hrs

Now
Speed= distance/time
= 200/2
= 100 mph

Imo C

E. 200 mph


The time for the first part of the trip is 300/60 = 5 hours. Thus, he has 7 - 5 = 2 hours to drive 200 miles. In order to achieve this, he has to drive at 200/2 = 100 mph.

Answer: C
