Question

If the speed is 1 unit every 8 minutes, what is time taken for |$-3\frac{7}{4}$| units?

• A. 19 minutes
• B. 28 minutes
• C. 32 minutes
• D. 38 minutes

Answer 1

The correct option is D 38 minutes

Here, the || refers to modulus or absolute value of a number.

First, let's find the absolute value of the given location and then multiply the distance with the unit time given.

$|-3\frac{7}{4}|$ = $3\frac{7}{4}$

On converting the mixed fraction, we get, $3\frac{7}{4}$ = $\frac{19}{4}$ units

Given:
Time taken for 1 unit = 8 units
So, time taken for $\frac{19}{4}$ units =$\frac{19}{4}$ $\times$ 8
= 19 $\times$ 2
= 38 minutes
