Lilly takes a train each day to work that averages 35 miles per hour. on her way home, her train ride follows the same path and averages 45 miles per hour. if the total trip takes 2.5 hours, which equation can be used to find n, the number of miles lilly's home is from her work?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
