This is a nonsense question.
14 miles on the route he took. 10 miles if you mean in a straight line.
The runner is running at a speed of 8 miles per hour.
The marathon runner is running at 26 miles per 2.5 hours (26 miles / 2.5 hours), or 10.4 miles per hour.
3.1 miles
You can never go wrong with changing the oil & the oil filter every 3,000 miles. Been doing that for all of my 44 driving years.
3 hours
that runner will run at 13 MPH
They would be running 7.5 mph.
It depends on the speed at which the runner is travelling.
It depends on the runner
Four runners complete a relay race in which each runner runs twice as far as the preceding runner. Together, they run a total of 30 miles. How far did the first runner run? 2 miles. 1+2+4+8 = 15. Together tey ran 15 times as far as the 1'st one ran.
Marathon... No Joke
