Question

$\text{The speed indicator is positioned}\frac{7}{5}miles$
before the warning sign board. What is the right location of the speed indicator on the number line?

• A. Between 0 and 1
• B. Between 0 and -1
• C. Between -1 and -2
• D. None of these

Answer 1

The correct option is C Between -1 and -2

$\text{Since}\frac{7}{5}\text{miles is placed before the warning}$
$\text{sign board, we need to plot}\frac{7}{5}\text{on the left side}$
$\text{of the warning board.}$

$\text{We know,}\frac{7}{5}=1\frac{2}{5}\text{which is a mixed number.}$

Since the indicator has to be be placed on the left side of '0', it can be termed $\text{as}\frac{-7}{5}.$

Hence, the location of the speed indicator is between -1 and -2 and at $\frac{2}{5}$ of the division as shown below.


Therefore, third option is the correct answer.
