The speed of the car is 50 mph and that of the plane is 300 mph.
Time taken by the car is 5 hours and that taken by the plane is 4 hours.
Step-by-step explanation:
Let the speed of the car is u mph and that of the plane is v mph.
So, v = 6u ............ (1)
Now, as per the given condition, we can write the equation as
⇒ {From the equation (1)}
⇒
⇒
⇒ u = 50 mph.
So, v = 6 × 50 = 300 mph.
And, the time taken by the car is hours and that taken by the plane is (5 - 1) = 4 hours. (Answer)
