One lap around a track is equal to one-fourth of a mile. a horse ran a distance of 9 laps in 2 minutes and 30 seconds. what was the horse’s average speed in miles per minute?

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

good luck on your studies! : )
