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?

Without any specific data provided for Airplanes A and C, it is not possible to determine their speeds or the distance they travel in 3 seconds. Therefore, we can only answer the questions related to Airplane B.
(a) To determine the speed of Airplane B, we need to find the slope of the distance-time graph. Since the graph is a straight line, the slope can be found by calculating the change in distance divided by the change in time.
The change in distance is 1600 - 400 = 1200 meters.
The change in time is 12340 - 0 = 12340 seconds.
The speed of Airplane B is 1200 meters / 12340 seconds = 0.097 meters/second.
(b) Since we do not have any data for Airplanes A and C, we cannot determine which airplane is the slowest.
(c) Similarly, since we do not have any data for Airplanes A and C, we cannot determine how far they travel in 3 seconds.
