To determine

To find: The value of the given expression.

Answer to Problem 1.1.1EP

The value of the given expressionis $30.6$ .

Explanation of Solution

Given:

The given expression is,

  $qr-vt$

The given values are,

  $\begin{array}{c}q=\frac{1}{2}\\ r=1.2\\ v=-6\\ t=5\end{array}$

Calculation:

The value of given expression is calculated as,

  $\begin{array}{c}qr-vt=\frac{1}{2}\left(1.2\right)-\left(-6\right)\left(5\right)\\ =0.6+30\\ =30.6\end{array}$

Therefore, the value of the given expression is $30.6$ .
