Question : Rubi goes to a multiplex at a speed of 3 km/h to see a movie and reaches 5 minutes late. If she travels at the speed of 4 km/h she reaches 5 minutes early, then the distance of the multiplex from her starting point is:
Option 1: 2 km
Option 2: 5 km
Option 3: 2 metres
Option 4: 5 metres
Correct Answer: 2 km
Solution : Let the distance be $x$ km. According to the question, Speed = $\frac{\text{Distance}}{\text {Time}}$ $\frac{x}{3}–\frac{x}{4}=\frac{5+5}{60}$ ⇒ $x=2$ Hence, the correct answer is 2 km.
