A 725 m long train passes a tunnel 235 m long in 48 seconds. Find the speed of the train.

• 42 km/h
• 72 km/h
• 36 km/h
• 100 km/h

Two trains start from places A and B, respectively, and travel towards each other at the speeds of 60 km/h and 50 km/h, respectively. By the time they meet, the faster train has travelled 110 km more than the slower train. What is the distance between A and B?

• 1100 km
• 1200 km
• 1150 km
• 1210 km

How many minutes wil Radha take to cover a distance of 1950 m, if she runs at a speed of 26 km/h?

A person walking at a speed of 7.2 km/h and crosses a bridge in 25 minutes. Find the length of the bridge (in metres)

• 1575
• 1960
• 3000
• 2000

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in (5/3)hours, it must travel at a speed of:

• 300 kmph
• 360 kmph
• 600 kmph
• 720 kmph

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

• 50 km
• 56 km
• 70 km
• 80 km

The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:

• 70 km/hr
• 75 km/hr
• 84.5 km/hr

• 87.5 km/hr
