Answer 1

Answer:

(a) [tex]Time= 119.05 \ min[/tex]

(b) [tex]Time= 9.26\ hr[/tex]

Explanation:

Given

[tex]File = 30GB[/tex]

Required

Download time

Solving (a): When Speed =4.2Mb/s

Speed is calculated as:

[tex]Speed = \frac{File\ Size}{Time}[/tex]

Make Time the subject:

[tex]Time= \frac{File\ Size}{Speed }[/tex]

Substitute values for File Size and Speed

[tex]Time= \frac{30Gb}{4.2Mb/s}[/tex]

Convert Gb to Mb

[tex]Time= \frac{30*1000Mb}{4.2Mb/s}[/tex]

[tex]Time= \frac{30000s}{4.2}[/tex]

Convert to minutes

[tex]Time= \frac{30000}{4.2*60}\ min[/tex]

[tex]Time= \frac{30000}{252}\ min[/tex]

[tex]Time= 119.05 \ min[/tex]

When converted, it is approximately 2 hours

Solving (a): When Speed =900Kb/s

[tex]Time= \frac{File\ Size}{Speed }[/tex]

Substitute values for File Size and Speed

[tex]Time= \frac{30Gb}{900Kb/s}[/tex]

Convert Gb to Kb

[tex]Time= \frac{30*1000000Kb}{900Kb/s}[/tex]

[tex]Time= \frac{30*1000000s}{900}[/tex]

[tex]Time= \frac{1000000s}{30}[/tex]

[tex]Time= \frac{100000}{3}s[/tex]

Convert to hours

[tex]Time= \frac{100000}{3*3600}hr[/tex]

[tex]Time= \frac{1000}{3*36}hr[/tex]

[tex]Time= \frac{1000}{108}hr[/tex]

[tex]Time= 9.26\ hr[/tex]
