Question

Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12meters per minute. He was at sea level after 30minutes of driving.

Answer 1

He was at sea level 360 meters after 30 minutes of driving.

Step-by-step explanation:

• Given data

        Time (T) = 30 min

        $\mathbf{\textrm{Descending rate}= 12 \ \frac{m}{min}}$

• It means he will move down into sea 12 meters in 1 minute.

• From unitary methods

          In 1 minute distance travel = 12 meters

       ∴ In 30 minute distance travel = 12× 30

       ∴ In 30 minute distance travel = 360 meters

• He was at sea level 360 meters after 30 minutes of driving.
