Answer:
Step-by-step explanation:
203 miles in 3.5 hrs....and 243 miles in 4.5 hrs
totaling : (203 + 243) miles in (3.5 + 4.5) hrs = 446 miles in 8 hrs
speed = distance / time
speed = 446 / 8
speed = 55.75 mph <==
Either positive or negative 180°.
Answer:
A. width = x - 4.5
B. 111 = 2(x + (x -4.5))
