Answer:
Airspeed in still air: 140 mph
Step-by-step explanation:
Let s represent the speed in still air. Recognize that the distance traveled is the same in either direction.
Also note that SF is north of LA.
Distance to SF from LA = Distance to LA from SF
(s-20)(mph)(4 hr) = (s+20)(mph)(3 hr)
Then:
4s - 80 = 3s + 60 => s = 60 + 80 + 140 (mph)
The airspeed of the plane was 140 mph in still air. With a tail wind, the plane is faster; with a headwind, slower.
Answer:
iM SORRY I DONT KNOW TRY 1/3
Step-by-step explanation:
First, find the difference between the original price and the reduced price;
65 - 45 = $20 difference
Then, divide the difference by the original amount;
20/65 ≈ 0.3077
Then, multiply this by 100 to convert the decimal into a percentage;
0.3077 * 100 = 30.77%
The percent of change would be about 30.77%
