Question 1062292
.
a car leaves an intersection traveling at an average speed of 56 miles per hour. 
ten minutes later a second car leave the same intersection and travels on a road making an angle of 112 with the first car, 
at an average speed of 54 miles per house. assuming the roads are straight, how far apart are the cars 
30 minutes after the first car has left?
~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
30 minutes after the first car has left, it was {{{56*(1/2)}}} = 28 miles from the intersection.

30 minutes after the first car has left, the second car was {{{(1/3)*54}}} = 18 miles from the intersection.

The distance under the question is 

{{{sqrt(28^2 + 18^2 - 28*18*cos(112^o))}}} = calculate.
