Question 279780: Hi, hope this is the right place. I have a uniform motion problem that has me stumped. It seems a bit different from the other problems I have worked on:
an executive drove from home at an average speed of 30 mph to an airport where a helicopter was waiting. He boarded the copter and flew to the corporate offices at an averages speed of 60 mph. Entire distance was 150 miles. The entire trip took 3 hours. Find the distance from the airport to the corporate office. Is it a trick question? Answer is 120 miles from corporate offices, but not sure how to set it up to get he right answer. Please help!

time equals distance divided by rate

[(150 - x) / 30] + (x / 60) = 3

300 - 2x + x = 180

120 = x
