Chapter SH, Problem 1.15APP

To determine

To Calculate: The reduced download time.

Answer to Problem 1.15APP

The reduced download time is $\text{2 min 33 s}$ .

Explanation of Solution

Given data:

The actual download time $=17\text{ min}$

Percent of reduction in time $=85\%$

Calculation:

As per the problem,

The actual download time $=17\text{ min}$

Percent of reduction in time $=85\%$

So, the reduced download time is $(100\%-85\%)=15\%$ of the actual download time.

Therefore,

Reduced download time $=\frac{15}{100}\times$ actual download time.

Reduced download time

  $\begin{array}{l}=\frac{15}{100}\times 17\text{ min}\\ =2\frac{11}{20}\text{ min}=2\text{ min}+\frac{11}{20}\text{ min}\times \frac{60\text{ s }}{1\text{ min}}\text{ [1 min}=60\text{ s]}\\ \text{=2 min 33 s}\end{array}$

Conclusion:

The reduced download time is $\text{2 min 33 s}$ .
