Question 1157943
A private jet flies the same distance in 15 hours that a commercial jet flies in 10 hours.  If the speed of the commercial jet was 98mph less than 2 times the speed of the private jet, find the speed of each jet.
<pre>Let speed of private jet be S
Then speed of commercial jet = 2S - 98
We then get the following DISTANCE equation: 15S = 10(2S - 98)
3S = 2(2S - 98) ------ Factoring out GCF, 5
3S = 4S - 196
3S - 4S = - 196
- S = - 196
Speed of private jet, or {{{highlight_green(matrix(1,6, S, "=", (- 196)/(- 1), "=", 196, mph))}}}
Now, do you think you can find the commercial jet's speed?
