A gazelle can run 73 feet per second for several minutes. A cheetah can run faster (88 feet per second) but can only sustain its top speed for about 20 seconds before it is worn out. How far away from the cheetah does the gazelle need to stay for it to be safe? (g = gazelle's starting distance from cheetah)
What is g > 300? The gazelle needs to stay more than 300 feet away from the cheetah in order to be safe.
