Question 1141376

Kirk can bike 32 miles in the same amount of time that his twin brother Karl can bike 24 miles. If Kirk bikes 2 mph faster than Karl, how fast does each man bike?
<pre>Let Kirk's speed be S
Then Karl's speed is, S - 2
We then get the following TIME equation: {{{matrix(1,3, 32/S, "=", 24/(S - 2))}}}
Solve this for S, Kirk's speed
SUBTRACT 2 from S to get Karl's speed
