Question

David is riding in a bike race That goes through a valley in a nearby mountain range. The table gives the altitude in feet above sea level for the five checkpoints in the race. Use the table to answer the questions.

Answer 1

a) You have to determine the distance between checkpoints 5 and 2, to do so, you have to calculate the difference between the altitude of both checkpoints.

Checkpoint 2: -43 ft

Checkpoint 5: 3,382 ft

`3382-(-43)=3425`

This result indicates that checkpoint 2 is 3,425ft below checkpoint 5.

b) The top of the hill is 532 ft above checkpoint 4, to determine the altitude of the top of the hill, you have to add this distance to the altitude to checkpoint 4.

Checkpoint 4: -176ft

Distance 532

`-176+532=356`

The top of the hill is 356ft above sea level.
