he Taieri Plain in New Zealand is 6 feet below sea level (or -6). If you care standing 3 feet above sea level, is your elevation the opposite of the elevation of the plain? Describe the steps you would follow with a vertical number line to find the answer.

Link can ride his bike 20 miles into a 3 mph headwind in the same amount of time he can ride 30 miles with a 3 mph tailwind. What is Link’s biking speed?

Give an example of a negative number from your life experience.

Danica can sail her boat 5 miles into a 7 mph headwind in the same amount of time she can sail 12 miles with a 7 mph tailwind. What is the speed of Danica’s boat without a wind?

In the 2010 winter Olympics, two skiers took the silver and bronze medals in the Men's Super-G ski event. The silver medalist's time was 1 minute 30,62 seconds and bronze medalist’s time was 1 minute 30.65 seconds. Whose time was faster? Find the difference in their times and then write the name of that decimal.

Negative fifteen is three more than a number y

Samila is sitting under her tarp at the ocean and decides to walk to the snack shack. She can walk 1.7 feet per second in the sand and 2.4 feet per second on the sidewalk. Her tarp is 25 feet away from the nearest point B along a straight boardwalk. The snack shack is 87 feet away from point B. (So the distance from B to C is 87 feet). Sidewalk Snack shack If she walks in the sand along a straight line to the sidewalk and then walks the rest of the way on the sidewalk, find an expression that gives the total time to reach the snack shack in terms of x, the distance from B to where she first reaches the sidewalk. T(x) = Find the minimum time it takes for Samila to reach the snack shack. (I'm looking for the TIME here.) DO NOT USE CALCULUS TO DO THIS. Minimum TIME required to get to snack shack = seconds. (Round to the nearst second)

Ben and Michael also participated in the long jump. Michael jumped 334 thousandths of a meter less than Kevin. Ben jumped farther than Michael but not as far as Kevin. Write a decimal to the thousandths that is greater than Michael's distance and less than Kevin's distance. Explain the reasoning you used.
