SOLUTION: A plane climbs from an altitude of 19,000 ft to a cruising altitude of 31,000 ft. The plane ascends at a rate of 3000 ft/min. How long will it take to reach cruising altitude?

Algebra ->  Equations -> SOLUTION: A plane climbs from an altitude of 19,000 ft to a cruising altitude of 31,000 ft. The plane ascends at a rate of 3000 ft/min. How long will it take to reach cruising altitude?      Log On

To find the time, you should divide the increment of the altitude by the rate of the plane's ascend


    time =  = 4 minutes.    ANSWER
