Tourist travels 1500 miles using two planes. the second plane averages 50 miles per hour faster than the first plane. the tourist uses the slower plane for the first 500 and the faster plane for the next 1000 miles. the total flying time is 6.5 hours. what is the speed of the first plane?

Answer

given,

tourist travels = 1500 miles

second plane averages 50 miles per hour faster than the first plane.

x = y + 50

The tourist uses the slower plane for the first 500 and the faster plane for the next 1000 miles.

total flying time = 6.5 hours

on solving equation

y = 86.67 mile/hr

x = 86.67 + 50

x = 136.67 mile/hr

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
