Answer:
The correct option is C.
Step-by-step explanation:
The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.
So total time taken by car is
It means total time taken by car is 1.5 hour.
The distance in first figure is 50 miles and the speed in second figure is 155 miles.
So total distance travelled by car is
It means total distance travelled by car is 105 miles.
The formula of speed is
Therefore option B represents the solution. Option B is incorrect.
Multiply both sides by 1.5 hours.
Therefore option D represents the solution. Option D is incorrect.
Divide both sides by speed.
Therefore option A represents the solution. Option A is incorrect.
Option C can not represent the solution, therefore option C is correct.
