When she arrived in Jerusalem after 1.5, point, 5 hours of driving, her altitude was 710 meters above sea level. We need to find the initial height from sea level . Let's find out:

Let N(t) be Noa’s altitude to sea level and time t .

.  where h is initial height we need to find.

She was 710 meters above sea level after 1.5 hours. So,

⇒
