Question

Solves the word problems –

Convert 54 km/hr. into m/s

Calculate Time-period of a simple pendulum if it takes 72 seconds to complete 24 oscillations.

A train is travelling at a speed of 100 km/hr. How long will it take to complete a journey of 500 km without stopping in between.

Ramesh takes 15 minutes to reach market from his house on this cycle. If the speed of his cycle is 4 m/s calculate the distance between his house and market?

​

Answer 1

1 15 m per second

2 The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

3 Explanation: If a train is travelling at a speed of 100 kmph, it will take 5 hours to complete a journey of 500 km.

4I think Ramesh should be applying to take part in the Olympics cycling sprint team.

15 * 30 = 450m. In km/h that is 3.6 * 30 = 3 * 30 + 0.6 * 30 = 90 + 18 = 108 km/h. The highest speed Sir Chris Hoy achieved in Keirin is 80 km/h.
