Question

The distance between two station is 640 km. A train takes five hours to cover the distance. What is the speed of the train. ​

Answer 1

Answer:

128

Explanation:

distance=640km

time=5 hours

speed= distance/time

=640/5

=128km/h

Answer 2

Answer: The speed of the train is $128 km/hr$.

Explanation:

Given: Distance between two stations $d = 640 km$

Time taken to cover the distance, $t= 5 hrs$

To find: Speed of the train, $s = ?$

Solution:

The rate of change in an object's position over time, or the rate of change in position per unit of time, is known as its speed.

Formula to calculate speed is:

$s= \frac{d}{t}$

Now putting the values of distance and time in the formula;

$s = \frac{640 km }{5 hrs} = 128 km/hr$

Therefore, speed of the train is $128 km/hr$.
