Answer 1

The information can be used to draw the attached model vertical number line created with MS Word

Part A: 1.1 miles above the top of the waterfall

Part B: 1.4 miles above the top of the waterfall

Part C: The value of zero is the location of the top of the waterfall

Part D: The distance down to go swimming, -1.4 miles is the same as the distance back to the top, as the absolute value of -1.4, |-1.4| = 1.4

|-1.4| miles = 1.4 miles

What is a number line?

A number line is a line marked with numbers at intervals to illustrate association between values in numerical operations.

 

The distance to go swimming = 1.4 miles down

The distance along the path to eat lunch = 1.1 miles down

Part A: The top of the waterfall can be taken as the base location for the measurement.

Locations below the waterfall can be taken as negative and locations above the waterfall can be taken as positive.

The relative vertical distance from the waterfall to the location lunch is eaten is -1.1 miles

• The height of the drone can be flown to be at opposite distance to the place for lunch is therefore 1.1 miles above the waterfall

Part B: The relative vertical distance of the location to swim safely from the top of the waterfall is -1.4 miles

Therefore;

• The drone needs to fly 1.4 miles vertically above the waterfall to be at opposite distance when swimming

Part C: The vertical distance of 0 miles of a location from the top of the waterfall indicates that the location is the same as the top of the waterfall

Therefore;

• The zero represents the top of the waterfall

Part D: Absolute value means to take all numbers as positive;

The vertical distance to hike down to go swimming = -1.4 miles

Vertical distance to hike back to the top of the waterfall = 1.4 miles

Using absolute values, we get;

Distance down to swim = |-1.4| = 1.4

Distance back to the top of the waterfall = |1.4| = 1.4

• The distance hiked down, 1.4 = The distance back to the top, 1,4

Therefore;

• The same distance is hiked in both directions.
