Jonah and Makayla are on a scuba diving tour of a reef. Jonah is at a depth of –20 feet and ascending at a rate of 0.25 foot per second. Makayla is at a depth of –12.5 feet and descending at a rate of 0.5 foot per second. Solve the equation 2(−20+0.25s)=−12.5−0.5s to find how many seconds s it will take for Makayla to be twice as deep as Jonah. Enter your answer as an integer or decimal.
