Answer:
40. 7 km. 11. d = 4.5 m, h = - 4.5 m
Step-by-step explanation:
d = | 4 - (- 3) | = 7 km
11. Depth (d) = sea level - Diver's distance according to water level
= 0 - ( - 4.5) m
= 0 + 4.5 m
= 4.5 m
Diver height (h) = sea level + Diver's distance according to water level
= 0+ ( - 4.5) m
= - 4.5 m
