The speed at which a certain computer can access the internet is 2 megabytes per second. How fast is this in megabytes per hour.

Ainat [17]

$Converting\ units:\\\\ 2\frac{megabytes}{second}\\\\ 1second=\frac{1}{3600}h\\\\ 2\frac{megabytes}{second}*\frac{1}{\frac{1}{3600}}=2\frac{megabytes}{second}*\frac{3600}{1}=7200\frac{megabytes}{second}\\\\If\ 1second=\frac{1}{3600}\ you\ must\ multiply\ 2*\frac{1}{3600}\ to\ convert\ 1\ second\\ into\ hour.$
