Answer:
Solve for X; whereas lb=pound, $=cost
1lb = $12.55
0.6lb = $X; therefore 6/10 lb = $X
Rewrite:
$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10
X=$7.53 for .6 lbs.
Answer:
Plane 1 travels 20 miles farther than plane 2 in an hour.
Step-by-step explanation:
To compare the distances, compare the speed of each plane. The speed of plane 1 is 290 miles per hour in d(t) = 290t.
Plane 2 travels 540 miles over 2 hours. Its speed is 540/2 = 270 miles per hour.
Plane 1 will travel 20 miles farther than plane 2 in an hour.
