Simplify 4.3^2-7?
= 4 × 3^2 - 7
= 4 × 9 - 7
= 36 - 7
= 29
77.5 = 12.5t
6.2 mins.
The scuba diver was at the sea bed from where the water surface is at 77.5 m height. The ascending speed of the diver is 12.5 m/minute.
a. If the diver take t minutes to reach the water surface, then the equation that models the situation is
77.5 = 12.5t ......(1)
b. If we consider the sea bed as a reference level i.e. zero height, then the sea surface will be at 77.5 m height.
Therefore, in that case, it is reasonable to write the distance 77.5 m as a positive number.
c. Solving the equation (1), we get, t = 6.2 minutes.
So, the diver will take 6.2 mins to reach the surface. (Answer)
