Question : A train covers a certain distance at a speed of 80 km/hr in 6 hours. Find the speed of the train for covering the same distance in 5 hours.
Option 1: 96 km/hr
Option 2: 86 km/hr
Option 3: 90 km/hr
Option 4: 88 km/hr
Correct Answer: 96 km/hr
Solution :
Given: A train covers a certain distance at a speed of 80 km/hr in 6 hours.
Use the formula, $\text{Speed}=\frac{\text{distance}}{\text{time}}$
Let the train's distance be $x$ km.
According to the question,
$80=\frac{x}{6}$
⇒ $x=480$ km
The speed of the train for covering the same distance in 5 hours $=\frac{480}{5}=96$ km/hr
Hence, the correct answer is 96 km/hr.
