Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r to represent the speed of the slower cyclist. b. What are the speeds of the two cyclists? What units? Slower Cyclist: Select an answer Faster Cyclist: Select an answer

Eric is driving an average of 39 miles per hour, and he is 109.2 miles away from home. After how many hours will he reach his home? Assume Eric will reach home after h hours. Write an equation to model this scenario. There is no need to solve it.

use the Y axis to represent distance and the X axis to represent time. Four race cars are heading for the finish line. Car 11 is in the lead and has 1.2 miles to go.  But he has engine trouble and is only traveling at a speed of 130 mph.     How long before car 11 crosses the finish line (where distance remaining  = 0).                                                                 Car 32 is in second and is .1 miles behind Car 11 (he has 1.3 miles to go).    He is traveling at a speed of 140 mph.  Add that line to your graph. Car 53 is in third and is .3 miles behind the leader (1.5 miles to go).  He is traveling at a speed of 165 mph. Car 94 is in last place, and is .5 miles behind the leader (1.8 miles to go).   He is gaining fast, at a speed of 185 mph. Remember, the x axis is time, and the y axis is distance to go. The winner will be_______________________                                                   Second place will go to ____________________________…

Joni planted two tree saplings in their garden on the same day. One tree sapling started out 25 inches tall and grew at a rate of 1.5 inches per week. Another tree sapling started out 35 inches tall and grew at a rate of 1 inches per week. After how many weeks were the two tree saplings the same height? weeks How tall were the saplings at this time? inches

In a 16 km cross-country ski race Brett skied the first 7 km at a constant speed and then increased his speed by 3 km/h for the last 9 km. If he finished the entire race in 1 hour and 20 minutes, what was his speed for the first 7 km?

You run along a path at a constant speed of 4.7 mph. How far do you travel in 1.7 hrs? In 3.8 hours?

4) The time a basketball player spends in the air when shooting a basket is called the​ "hang time." The vertical leap L measured in feet is related to the hang time t measured in seconds by the equation L=4t2. Suppose that a basketball player has a vertical leap of 3 feet 7 inches. Find the hang time for this leap.
