Answer 1

Answer: (B)

$450$

Given: The size of song downloaded from internet $=4$ megabytes.
Per second $=256$ kilobytes
$2$ hours $=7200$ seconds.
For $7200$ seconds to download $=7200\times 256=1843200$ kilobytes
Convert kilobytes to megabytes,
So, $\frac{843200}{1024}=1800$
Edwin download in $2$ hours $=$ $\frac{1800}{4}=450$
