You can put this solution on YOUR website! a plane has 600 miles to travel. it has flown for 1 hour at 300 mph when the air control tower radios and tells the pilot that due to crowded conditions it will be able to land on the runway.
what speed, or rate, should the pilot travel at for the next 2 hours?
:
From the information give we know the plane as traveled 300 mi when it is called. (300 mph for 1 hr)
:
let s = speed for the last two hrs of the trip
:
Write a distance equation, dist = speed * time
300 + 2s = 600
2s = 600 - 300
2s = 300
s = 300/2
s = 150 mph for the last 300 mi to arrive in two hrs
