Continent: South America. 95 km/h cos 300 vpE = = = 82 km/h e = cos-1 82 km/h = 730 285 km/h 285 km/h sin 730 = 273 km/h 95 km/h sin 300 = 47.5 km/h = 273 km/h + 47.5 km/h RN = 320 km/h VR = 320 km/h north Chapter Review Problems pages 78-79 page 78 Section 4.1 Level 1 19. Changtu is the closest city to Las Piedras's antipodal point (11 km). Find the speed of each plane if after 2 hours the planes are 3200 km apart. The Pythagorean Theorem says A2 + B2 = C2, where C is the side opposite the right angle. Opposites examples: Cheshunt is a few miles to the north of London. In the above diagram, the direction of: A from O is N30ºE. B from O is N60ºW. They are separated by 5km . B: 30 km/h. d) A racecar goes around an oval track at 220 km/h. To do so, the velocity of boat relative to the ground ($\vec{v}_b$) should be perpendicular to the flow velocity ($\vec{v}_w$). The resultant is 10.0 km. What is the speed of car moving in the opposite direction if it meets the two cars at an interval of 4 minute: Velocity calculator helps you to find the velocity using the average velocity formula with the given distance and time values. A. North-West b. South-East c. North-East d. North . Let the computer write the numbers. How far to the north and west does the airship in problem 7 travel after 15.0 minutes? are not listed here. Question 495658: Two planes start from the same airport and fly in opposite directions. If the minute hand points to east, in what direction will the hour hand point? You can’t ignore the fact that many criminals never go to prison. Hence, the answer is option B. Coordinates: 30.262, 122.418. The antipodal city to Las Piedras is Changtu. D from O is S80ºW.
