Question

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

Answer 1

(2 things/sec) x (3600 sec/hour) = 7200 things/hour

Answer 2

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