Question

Carroll bikes 1 kilometer east, 4 kilometers north, and then 5 kilometers east again. How far is Carroll from her starting position, to the nearest tenth of a kilometer?

Answer 1

7.2 km away from her starting point

Answer 2

Distance of Carroll from the starting point is 7.2 km.

Explanation:

Carroll bikes 1 km east, then 4 kilometers North, and 5 kilometers east again.

We have to calculate the distance from the starting point of Carroll.

Here we can find the distance finally from the starting point with the help of Pythagoras theorem.

Diagonal² = (Side 1 of the rectangle)² + (Side 2 of the rectangle)²

Diagonal² = 4² + 6²

= 16 + 36

= 52

Diagonal = √52

= 7.21

≈ 7.2 kilometers

Therefore, distance of Carroll form her starting point is 7.2 kilometers.
