Two boats leave from the same point and the same time. If one travels north at 15 mph and the other travels east at 20 mph, how fast will the distance between them be changing after 2 hours?
Two trains leave Union station at the same time. The first train is travelling on a track with bearing 116º at 95 km/h. The second train is travelling on a track with bearing 271º at 80km/h. Determine the distance between the trains 3 hours after they leave the station.
Car A, traveling south at 30 feet per second, is 400 feet due north of an intersection. Car B, traveling west at 40 feet per second, is 300 feet due east of the same intersection. At this point in time how fast, in feet per second, is the distance between Car A and Car B changing? a) 42 b)44 c)46 d)48
Two trains are traveling on the same track and in the same direction. The first train, which is behind the second train, blows a horn whose frequency is 269 Hz. The second train detects a frequency of 290 Hz. If the speed of the second train is 13.7 m/s, what is the speed of the first train? I used the following equation and set Fo to 290Hz and Fs to 269hz. + on top and - on bottom. I figured...
Two trains are traveling on the same track and in the same direction. The first train, which is behind the second train, blows a horn whose frequency is 266 Hz. The second train detects a frequency of 284 Hz. If the speed of the second train is 13.8 m/s, what is the speed of the first train?
Constants Part A City A lies directly west of city B. When there is no wind, an airliner makes the round trip flight of distance s between them in a flight time of ti while traveling at the same speed in both directions When a strong, steady wind is blowing from west to east and the airliner has the same air speed as before, the round trip takes a flight time of t2 How fast is the wind blowing? km/h...
Two people start from the same point. One walks east at 3 mi/h and the other walks northeast at 2 mi/h. How fast is the distance between the people changing after 15 minutes?? Thanks for help !!
Two parallel paths 15 m apart run east-west through the woods. Brooke jogs east on one path at 2 km/h, while Jamail walks west on the other path at 3 km/h. If they pass each other at time t = 0. how far apart are they 7 s later and how fast is the distance between them changing at that moment? (Use decimal notation. Give your answer to three decimal places.) The distance between them at t = 7 is...
