1 second = 2 megabytes

$1\frac{1}{2}\ seconds=3\ megabytes$

2 seconds = 4 megabytes

Step-by-step explanation:

Given,

Time taken to download 5 megabytes = $2\frac{1}{2}=\frac{5}{2}$ seconds

$\frac{5}{2}\ seconds = 5\ megabytes$

Multiplying both sides by $\frac{2}{5}$ to find unit rate

$\frac{2}{5}*\frac{5}{2}\ second = \frac{2}{5}*5\\1\ second = 2\ megabytes$

1 second = 2 megabytes

$1\frac{1}{2}\seconds = \frac{3}{2}\ seconds$

$\frac{3}{2}\ seconds = \frac{3}{2}*2$

$\frac{3}{2}\ seconds = 3\ megabytes$

$1\frac{1}{2}\ seconds=3\ megabytes$

2 seconds = 2*2 megabytes

2 seconds = 4 megabytes
