Noa drove from the Dead Sea up to Jerusalem, and her altitude increased at a constant rate of 740 meters per hour. When she arrived in Jerusalem after 1.5 hours of driving, her altitude was 710 meters above sea level. Let A represent Noa's altitude (in meters) relative to sea level after t hours. Complete the equation for the relationship between the altitude and number of hours.

Let t = time in hours:

 

A = 740*t + k

 

710 = 740*1.5 + k

 

710 = 1110 + k

 

k = 710 - 1110 = -400

 

A = 740*t - 400
