Question

Sunitha travelled \[\text{15km 265m}\]by bus, \[\text{7km 6m}\]by car and \[\text{400m}\]by foot in order to reach her school. How far is her school from residence?

Answer 1

Hint: In order to find the distance from her residence to school, we must be considering all the distances she has travelled by all means of transportation. After considering all the distances, we will be summing up all the distances in order to obtain the total distance from her school to residence.

Complete step by step answer:
Now let us learn more about distances in mathematics. The distance between two points is nothing but calculating or finding the total length or how far the two points are from each other. In mathematics, generally we will be using the Pythagoras theorem in finding the distances. If the distances do not form any pattern we can simply add up the distances to find the total distance.
Now let us calculate the total distance from Sunitha’s residence to school.
We are given that,
Distance travelled by bus \[\text{=15km 265m}\]
Distance travelled by car\[\text{=7km 6m}\]
Distance travelled by foot\[\text{=400m}\]
Now, let us calculate the total distance by adding up the distances.
Upon adding, we get
\[\begin{align}
& \,\,15km \,\,\,\,\,265m \\
& + 7km \,\,\,\,\,\,\,\,\,\,\,6m \\
& +\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, 400m \\
& \overline{ \,\,22km \,\,\,\,\,671m} \\
\end{align}\]
\[\therefore \] The total distance from Sunitha’s residence to her school is \[\text{22km 671m}\].

Note: While solving this problem, we can note that if the units given are suitable to perform operations. If not, we must convert all of the measurements into a single unit by using a conversion method.
In the above problem, we can express the obtained answer in metres as shown below.
\[\text{22km 671m}=22\times 1000+671=22000+671=22671m\]
