FUN RUN SPRINT
This is Angela’s first time in the three mile Fun Run and she is finding it a little tough. In fact, she has just completed the first two miles, and as she looks at her watch she says to herself (breathlessly): ‘I’m only averaging four miles an hour. Oh dear, I wanted to average six miles per hour for this run. I must go a bit faster.’
How fast will she have to run the final mile in order to get her average speed for the whole Fun Run up to 6 mph?
