Two trains leave stations 216 miles apart at the same time and travel toward each other. one train travels at 85 miles per hour while the other travels at 95 miles per hour. how long will it take for the two trains to meet

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
