Question

Nour drove from the dead sea up to amman, and her altitude increased at a constant rate. When she began driving, her altitude was 400400400 meters below sea level. When she arrived in amman 222 hours later, her altitude was 100010001000 meters above sea level. Let aaa represent nour's altitude (in meters) relative to sea level after ttt hours. Complete the equation for the relationship between the altitude and number of hours.

Answer 1

Equation representing altitude and number of hours will be "a = 700t - 400"

Step-by-step explanation:

If we plot altitude on y-axis and time or duration of travel on x-axis of the graph then the location of Nour at t = 0 will be represented by (0, -400)

Now at t = 2 hours location will be at the point (2, 1000).

Since altitude is increasing at a constant rate, graph will be a linear graph represented by y = mx + b

Where slope of the line m = $\frac{y-y'}{x-x'}$

m = $\frac{1000+400}{2-0}$

m = 700

And y intercept b = -400

Therefore, equation of the line will be y = (700)x - 400

If Nour's altitude is represented by 'a' and time 't' then the equation will be

a = 700t - 400
