Question

bangalore is 1200km frm new Delhi by air and 1500km by train .If it takes 2hours by air and 20hours by train calculate the ratio of the average speeed

Answer 1

Distance to Bangalore from Delhi by air = 1200km
Time taken to reach by air = 2hours
Speed = Distance / Time
= 1200/2 km/hr
= 600km/hr

Distance to Bangalore from Delhi by train = 1500km
Time taken to reach there = 20hours
Speed = Distance / Time
= 1500/20 km/hr
= 75km/hr

Ratio of average speed = 600/75 km/hr
= 8km/hr

So, ratio of their average speed is 8km/hr.
