1. you are downloading an episode of the show \community\ from netflix. the video file is 1gb. your home internet speed is 40mbps. how long does it take you to download your episode in seconds? be sure to convert your units appropriately.

answer

Explanation:

Step1: Convert MB to Megabits (Q3)

Since 1 Byte = 8 bits, $7.5 \text{MB} = 7.5 \times 8 = 60 \text{Mbps}$

Step2: Calculate upload time (Q3)

Time = $\frac{\text{Total Data}}{\text{Speed}} = \frac{60}{0.75} = 80$ seconds

Step3: Convert GB to Megabits (Q4)

1 GB = 1024 MB, so $1 \text{GB} = 1024 \times 8 = 8192 \text{Mbps}$

Step4: Calculate download time (Q4)

Time = $\frac{\text{Total Data}}{\text{Speed}} = \frac{8192}{40} = 204.8$ seconds

Answer:

1. 80 seconds
2. 204.8 seconds
