A bus covers a distance of 2.45 km in 2 min. What is the speed of bus?​

The speed of the bus is 74.242 kilometers per hour.

Step-by-step explanation:

Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus (), in kiometers per hour, is determined by following kinematic expression:

(1)

Where:

- Travelled distance, in kilometers.

- Time, in hours.

If we know that and , then the speed of the bus is:

The speed of the bus is 74.242 kilometers per hour.

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
