Question

A bus started its journey from Ramgarh and reached devgarh in 44min with its average speed 50km/h. if the average speed increased by 5km/h, how much time will it take to cover the same distance?​

Answer 1

Answer: 40 minutes

Step-by-step explanation:

Original speed = 50 km/ hr

Original time = 44 min=11/15 hr

Distance = Speed × Time

= 11/15 × 50 = 110/3 km

New speed = 55 km/hr

Distance = 110/3 km

New time = Distance / Speed

=(110/3 )/55 =110/(55 ×3)

=2 /3 hr

=2/3 ×60 min

New time = 40 mins
