Step-by-step explanation:
(a^2+3b)/(c-2d)
substitute a=3,b=8,c=2,d=5
(3^2+3(8))/(2-2(5))
=(9+24)/(2-10)
=33/(-8)
=-4.125

<span>time for airplane = 11 am to 1 pm = 2 hr
distance travelled by plane = 2a ------- (speed of plane is a mph)
time for auto = 3 am to 1 pm = 10 hr
distance travelled by plane = 10(a – 200)
2a = 10(a – 200)
8a = 2000
a = 250 mph ----- plane
and 250 – 200 = 50 mph ----- auto </span>
