CAPE Physics Unit 1 · 1999 · Paper 2 · Question 2(i)

A ship maps the sea bed using high-frequency sound waves. Table 1 shows the distance from the ship's starting point and the time for the signal to return from the sea bed. The depth at Point A (0 m distance) is 100 m.

Assuming that the ship travels in a straight line and the depth of the sea bed at Point A is 100 m, calculate the depth at Point B. Hence, complete the Table 1 above. Put calculations in the space below.
