Question 1102175
.
<U>1 - Physics style solution</U>


<pre>
Their relative speed is 60 km/h + 40 km/h = 100 km/h.


It means that the distance between them decreases at the rate of 100 km/h.


Hence, they meet each other in  Time = {{{Distance/Rate}}} = {{{350/100}}} = 3.5 hours.


At this time Andy will be 40*3.5 = 140 miles from Toontown.
</pre>


<U>2 - Algebra style solution</U>


<pre>
Let "t" be the time they meet each other.


To that moment Andy will cover the distance of 60*t miles, while Michael will cover 40*t miles. 

In all these distance cover the whole/entire distance of 350 miles, which gives you an equation


60t + 40t = 350,     or   

(60+40)*t = 350  ====>  100t = 350  ====>  t = {{{350/100}}} = 3.5 hour.


Thus we obtained again this time interval of 3.5 hours till the meeting moment,

and Andy will cover his 3.5*40 = 140 miles from Toontown.
