Two small planes leave sacramento and la, which are 380 miles apart, and travel toward each other. if one plane travels 30 miles per hour faster than the other one and they meet in an hour, what are their respective speeds?

The sum of their speeds is 380 miles per hour. The difference of their speeds is 30 miles per hour. Then the faster plane is traveling at
.. (380 +30)/2 = 205 miles per hour

The slower plane's speed is 30 miles per hour less, so it is traveling at
.. 205 mph -30 mph = 175 miles per hour

I’m pretty sure the answer is a
