Speed  Time and Distance Examples

Here is some example of speed and distance of example 1. This is the basic theory of speed Time and Distance which is applied in question to obtain answers here is speed.

Basic Formula of speed and distance

Distance = Speed x Time

Speed = Distance / Time

Time = Distance / Speed

Example 1 :

Amir by a car passes a1200 m long road in 4 minutes. What would be his speed in km/hr ?

Answer: Speed = (1200 / 4x 60) m/sec = 5m / sec

Convert it into km/hr = 5x 18/5 = 18km/hr

 

Example 2 :

A girl goes to his college from his house at a speed of 3 km/hr and return at speed of 2 km/hr. if he takes 5 hours in going and coming, the distance between his house and college is:

Answer: Average speed = (2 x 3 x 2 / 2 + 3) km / hr.

Distance between his house and college he travailed in 5 hours: (12/ 5x 5) km = 12 km.

The distance between his house and college is : (12 / 2) = 6 km.
