A bus started its journey from Ramgarh and reached Devgarh in 44 minutes at an average speed of 50 km/h. If the average speed of the bus is increased by 5 km/h, how much time will it take to cover the same distance?

Answer : 40 mins

Solution:

Description for Correct answer:
Distance between Ramgarh and Devgarh = $\Large \frac{50 \times 44}{60}$ = $\Large \frac{110}{3}$ km

New speed = 55 kmph

= $\Large \frac{55}{60}$ km / minute

$\Large \therefore$ Required time = $\Large \frac{\ Distance}{ \ Speed}$

= $\Large \frac{110}{3} \times \frac{60}{55}$ = 40 minutes
