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

Each hour has 60 minutes, and each minute has 60 seconds.

So, each hour has 60*60=3600 seconds.

thus, i second is    1/3600 hour.


The speed of the internet is:
 $\frac{2megabytes}{second}= \frac{2megabytes}{1/3600hour}=2\cdot3600 \frac{megabytes}{hour}=7200\frac{megabytes}{hour}$


Answer: 7200 megabytes/hour
