Question

Yolanda is riding in a bike race that goes through a valley and 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,CheckpointAltitude(feet above sea level)12,2242- 13731,5714-305218(8) How much lower is Checkpoints than check out 2909 i lower

Answer 1

Step 1

Write the given checkpoint altitude

Checkpoint 1 = 2224

Checkpoint 2 = -137

Checkpoint 3 = 1571

Checkpoint 4 = -39

Checkpoint 5 = -218

Step 2:

a) How much lower is checkpoint 5 than checkpoint 2

You will subtract checkpoint 5 altitude from checkpoint 2

`\begin{gathered} =\text{ -137 - (-218)} \\ =\text{ -137 + 218} \\ =\text{ 81 f}eet \end{gathered}`

b) Altitude of the top hill that is 365 above checkpoint 5.

`\begin{gathered} \text{Altitude of the top hill = 365 - 218 } \\ \text{Altitude of the top hill 365 above checkpoint 5 = 147} \end{gathered}`
