Question

A cliff diver begins her dive off of the cliff from a elevation of 10 4/5 meters. If her dive into the water results in a change in elevation of -13 1/5 meters, then at, what elevation does she finish her dive?

Answer 1

To find at what point she finished her dive we add the quantities given:

`10(4)/(5)-13(1)/(5)=(54)/(5)-(66)/(5)=-(12)/(5)=-2(2)/(5)`

Therefore she finished her dive at an elevation of -2 2/5.
