Question

The distance between two places A and B is $3km760m$ . A boy travels from A to B and then B to A every day. How much distance does he travel in $8$ days ?

Answer 1

Hint: If you need to answer these types of questions, then you need to be clear with the language. Unless and until you understand the question clearly, you will not be able to come up with a solution. In the question, we are given a word problem in which we are provided with the distance between two places A and B. A boy travels from place A to B and then returns from B to A everyday and we are asked to find out the distance covered by him in eight such days. Which means multiply 2 for distance between A to B and finally 8 to get the required distance.

Complete step-by-step answer:
So, we have the distance between the places A and B as $3km760m$ .
We convert this distance from kilometres and metres to metres for the sake of convenience in calculations.
Now, we know that $1$ kilometres equals to $1000$ metres. So, multiplying the number of kilometres by $1000$ in order to convert it to metres.
So, we get the distance between the places A and B as $3,760m$ .
A boy travels from place A to B and returns from B to A everyday.
So, the distance travelled by him each day is twice the distance between the two places.
So, the distance travelled by the boy each day $=2\times 3760m=7,520m$
Now, the boy continues to travel for eight days.
So, the distance travelled by the boy in $8$ such days is $=8\times 7520m=60,160m$
Now, converting the distance travelled by the boy in eight days into kilometres and metres so as to match the format of the question, we get,
 $60,160m=60km160m$
Hence, the boy travels a total distance of $60km160m$ in eight days.
So, the correct answer is “ $60km160m$ ”.

Note: The above-mentioned method can be remembered as a complete process for solving these types of questions. Be careful with the language while attending these types of questions, because there are many questions which may confuse you with the tricky and typical language. These types of questions are easy to solve when you are writing an exam as it takes less time to solve when you are thorough with this concept and have practised ample amounts of questions.
