# Madhre is standing in the middle of a bridge which is 20 m above the water level of a river. If a 35 m deep river is flowing under the bridge then the vertical distance between the foot of Madhre and bottom level of the river is:

a. 55m

b. 35m

c. 20m

d. 15m

**Solution:**

To solve the above word problem we will follow the properties of integers. We know that the integers are closed under addition, subtraction and multiplication. Let us represent the situation with the help of diagram as shown below:

From the given word problem and the above figure the given parameters are:

The distance from top layer of the river till the foot of Madhre = 20 m

Depth of River = 35 m

The required vertical distance = 20 m + 35 m = 55 m

Therefore, the vertical distance between the foot of Madhre and bottom level of the river is 55m.

**✦ Try This: **Issac is standing 6m away from the tower. At a distance of 3m from the tower there is a bird lying on the ground. Calculate the amount of distance to be covered by Issac to save the bird.

Distance between the tower and Issac = 6m

Distance between the bird and the tower = 3m

To calculate the amount of distance covered by Issac to save the bird we will use the property of integers.

The distance traveled by Issac = 6m - 3m = 3m

## Madhre is standing in the middle of a bridge which is 20 m above the water level of a river. If a 35 m deep river is flowing under the bridge, then the vertical distance between the foot of Madhre and bottom level of the river is: 55m, 35m, 20m, 15m

**Summary:**

If a 35 m deep river is flowing under the bridge which is 20 m above the water level of a river then the vertical distance between the foot of Madhre and bottom level of the river is 55m.
