Question 1064448

supposs you have entered a 73-mile biathlon that consists of a tun and a bicycle race. during your run, your average velocity is 5 miles per hour, and during your bicycle race, your average velocity is 29 miles pet hour. you finish the race in 5 hours. what is the distance of the run? what is the distance of the bicycle race?
<pre>Let distance of the run be D
Then distance of the bicycle race = 73 - D
We then get the following TIME equation: {{{D/5 + (73 - D)/29 = 5}}}
Solve this equation for D, the distance of the run
Subtract value for D from 73 to get the distance of the bicycle race
That's it....nothing COMPLEX and/or CONFUSING!
