Three airplanes are traveling at constant speeds.
For each, the distance traveled depends on time, as shown below.
Airplane A
Time
(seconds)
Distance
(meters)
Airplane B
y40080012001600x12340
Airplane C
is the distance in meters
is the time in seconds
Answer the questions below about the airplanes.
(a) What is the speed of each airplane?
(b) Which airplane is the slowest?
Airplane A
Airplane B
Airplane C
(c) How far does each airplane travel in 3 seconds?
(a) To determine the speed of each airplane, we divide the distance traveled by the time taken.
The speed of Airplane A can be found by dividing the distance of 2400 meters by the time of 12 seconds:
Speed of Airplane A = 2400/12 = 200 meters per second
The speed of Airplane B cannot be determined as the distance and time data provided are not sufficient.
The speed of Airplane C cannot be determined as no distance or time data is given.
(b) Since we cannot calculate the speed of Airplane B and Airplane C, we cannot determine which one is the slowest.
(c) Since the distance traveled by Airplane A in 3 seconds is not given, and no data is provided for Airplane B and Airplane C, we cannot determine how far each airplane travels in 3 seconds.
