Question

The speed indicator is positioned $\frac{7}{5}$ km before the warning sign board. Which 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 the above

Answer 1

The correct option is C Between -1 and -2

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

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

Since the indicator has to be be placed on the left side of '0', it can be termed 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.

Hence, option (c) is the correct answer.
