Question 61544
let the distance from Portland to El Paso be x miles
the speed of the plane is 303 m.p.h
the speed of the car is 50 m.p.h.
time taken by the plane to fly the distance is x/303 hrs.
time taken bythe car to travel the same distance is x/50 hrs.
but it is given that
x/50 -x/303 =35.42
x(1/50-1/303) =35.42
x(303-50)303*50=35.42
253*x =35.42*303*50
x=( 35.42*303*50)/253
 = 2121 miles
you can check the answer by plugging in the values in the equation.
good luck !!!
