Question

A lap around a motocross track is a mile. How many laps do you need to complete to finish a $6$ -mile race?

Answer 1

Hint: At first, we need to understand that one lap means a complete loop. Then, as we are provided the equivalent of one mile as one lap, we can find what is the equivalent of six miles by simply applying the unitary method.

Complete step-by-step solution:
Motocross tracks or any other tracks like running tracks are of the shape of a closed loop. That means, the starting point and the end point are identical. One lap is defined as the completion of one round of the loop. This means that if we start from the starting point, run on the track and then again reach the starting point, then it is said that we have completed a lap.
Now, it is given the problem that one lap of the motocross track is $1mile$ . We are required to find out how many laps it will take to cover $6miles$ on the motocross track. Since both the values are given in the same measuring unit, that is mile, we do not need to convert the mile into any other unit of measurement like feet or yards or even unit of any other measurement system like kilometer. We can simply use the unitary method to solve this problem. So,
$\begin{align}
  & 1mile=1lap \\
 & \Rightarrow 6miles=\left( 1\times 6 \right)laps=6laps \\
\end{align}$
This means that if one lap is equal to one mile, then six laps will be equal to six miles.
Therefore, we can conclude that to finish a $6$ mile race, we need to complete $6$ laps.

Note: These problems are very easy to solve but mistakes are still possible. If two different units had been mentioned, we would have to convert one unit into another as convenient and then solve similarly. Also, if instead of a whole number, we get a decimal and we are asked the number of complete laps, then we need to take into consideration the lowest integer value like $6$ for $6.14$ .
