Answer 1

Given: Mara runs certain distance.

To find: What was the total distance of her run?

Solution:

• Now we have given that Mara runs a certain distance as follows:

                 3 km towards north and 4 km towards south.

• So after observing the directions, we found that the the figure formed will be a right angled triangle.

• So to find total distance we will use Pythagoras theorem, where hypotenuse will show the total distance.

                 hypotenuse = √(3)² + (4)²

                 hypotenuse = √9 + 16

                 hypotenuse = √25

                 hypotenuse = 5 km

• Total distance = 3 + 4 + 5 = 12 km

Answer:

           So the total distance Mara ran is 12 km
