The difference between the distances flown by these birds -
D[2] - D[1] = 640 - 490 = 150 Km.
We have the graph given in the question.
We have to find the difference in the distances flown by these two birds after 3 hours of flight.
What is the general equation of a line ?
The general equation of a line is -
y = mx + c
According to the question -
The slope of the line is -
m = 400/5 = 80
The y - intercept of the line is 0. Therefore → c = 0.
Therefore, the equation of the line will be -
y = 80x
The distance covered by Bird 1 →
D[1] = initial distance + 80 x 3 = 250 + 240 = 490 Km.
The distance covered by Bird 2 →
D[2] = initial distance + 80 x 3 = 400 + 80 x 3 = 400 + 240 = 640 Km.
Therefore, difference between the distances flown by these birds -
D[2] - D[1] = 640 - 490 = 150 Km.
