Zane is a dangerous fellow who likes to go rock climbing in active volcanoes. One time, when he was 202020 meters below the edge of a volcano, he heard some rumbling, so he decided to climb up out of there as quickly as he could. He managed to climb up 444 meters each second and get out of the volcano safely. Graph Zane's elevation relative to the edge of the volcano (in meters) as a function of time (in seconds).

Channel 2 gives the weather every 10 minutes starting at 5:10 A.M. Channel 4 gives the weather every 12 minutes starting at 5:10 A.M. A. When is the next time the two channels will give the weather at the same time? Explain your reasoning.. B The expression 48 +40 gives the number of minutes that the two channels spend on weather reports in the early morning. Use the distributive property to rewrite the sum as a multiple of a sum whose addends have no common factors.
