Answer: 7.1 meters
Explanation:
Given that :
Height of platform from which Doug dived = 5 meters above water
Doug's position after diving = 2.1 meters below water surface
How far does Doug's dive take him?
Distance above water surface to water surface = 5m
Final position to water surface = 2.1 meters
Hence, total distance covered after dive ;
5 meters + 2.1 meters = 7.1 meters
