Answer : Jeni's displacement from the starting point is, 111.8 meter.

Step-by-step explanation :

To calculate the Jeni's displacement from the starting point we are using Pythagoras theorem in ΔABC :

(Hypotenuse)^2=(Perpendicular)^2+(Base)^2

(AC)^2=(AB)^2+(BC)^2

Given:

Side AB = 100 m

Side BC = 50 m

Now put all the values in the above expression, we get the value of side AC.

(AC)^2=(AB)^2+(BC)^2

(AC)^2=(100)^2+(50)^2

AC=\sqrt{(100)^2+(50)^2}

AC=111.8m

Thus, the Jeni's displacement from the starting point is, 111.8 meter.

A bus covers a distance of 2.45 km in 2 min. What is the speed of bus?​
Vladimir [108]

Answer:

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 (v), in kiometers per hour, is determined by following kinematic expression:

v = \frac{s}{t} (1)

Where:

s - Travelled distance, in kilometers.

t - Time, in hours.

If we know that s = 2.45\,km and t = 0.033\,h, then the speed of the bus is:

v = \frac{s}{t}

v = 74.242\,\frac{km}{h}

The speed of the bus is 74.242 kilometers per hour.
