Question

A cross-country relay race was arranged between two towns of Usmanpur and Rampur. Each participant ran $750$ m with the flag and handed over the flag to the next runner. If $62$ participants ran this distance from the starting point to the finishing point, what is the total distance travelled by them? Give the answer in kilometers?

Answer 1

Hint: We have given that the distance travelled by one participant is $750$ m and total number of participants is $62$. We have to multiply distance travelled by one participant with the total number of participants to get the total distance. Then, convert the distance into kilometers.

Complete step-by-step answer:
We have given that in a relay-race each participant ran $750$ m with the flag and handed over the flag to the next runner.
Also, we have given that $62$ participants ran this distance from the starting point to the finishing point.
We have to find the total distance travelled by them.
As given one participant ran $750$ m.
So, $62$ participants ran $750\times 62=46500\text{ m}$
We have to give the answer in kilometers.
We know that $1\text{ m =}\dfrac{1}{1000}\text{ km}$
So,
$\begin{align}
  & 46500\text{ m }=\dfrac{46500}{1000}\text{ km} \\
 & \text{= 46}\text{.5 km} \\
\end{align}$
So, the total distance travelled by all participants is $\text{46}\text{.5 km}$.

Note: We have asked to give answers in kilometers, so it is important to convert the units. If students don’t convert the units, marks will be deducted. Also, some students may try to solve this question using the distance-speed formula, which is $\text{distance=speed }\!\!\times\!\!\text{ time}$ but they will not get the answer. Try to read the question twice and understand the information given and then solve the question.
