Question : A bus covers a distance of 45 km in 45 minutes. If its speed is decreased by 20 km/hr, then what will be the time taken by it to cover the same distance?
Option 1: 62.5 minutes
Option 2: 67.5 minutes
Option 3: 78.5 minutes
Option 4: 72.5 minutes
Correct Answer: 67.5 minutes
Solution :
A bus covers a distance of 45 km in 45 minutes.
Speed of the bus $= \frac{45}{45}×60=60$ km/hr
Its speed is decreased by 20 km/hr.
$\therefore$ New speed = 60 – 20 = 40 km/hr
1 hour = 60 minutes
$\therefore$ New time to cover same distance $= \frac{60}{40}×45=\frac{135}{2}=67.5$ minutes
Hence, the correct answer is 67.5 minutes.
