Question

A plan travels at a speed of 213miles per hour. Work out the estimate for the number of seconds the plane takes to travel 1 hour

Answer 1

3600 seconds

Explanation:

For a single hour, there are 60 minutes, and there are 60 seconds in each minute. So we have to multiply 60 x 60 to get 3600 seconds. It is an approximate answer, but of course being exact will still make you all the more correct. :)
