Q: A automobile travelling at 69% of its maximum speed travels 50 kilometres in 1 hour 40 minutes. What is the car's true speed?
-
A
65 km/hr
-
B
70 km/hr
-
C
45 km/hr
-
D
80 km/hr
Answer:
Explanation:
Distance = Speed x Time
50 km = X * (6/9) * (5/3)
50 km = X * (10/9)
Solving for X, we get:
X = 50 km / (10/9) = 50 km * 9/10 = 45 km/hr.
The actual speed of the car is 45 km/hr.
