You have jogged 5 miles from the park at a rate of r miles per hour. on your way back to the park your average speed increases by 1 mile per hour a) write an expression for the time t(in hours ) it takes to jog 5 miles from the park as a function of your average speed r ( in miles per hour ) b) when you run back to the park, your average speed increases by 1 mph. write an expression representing your new speed. c) write an expression for the time t(in hours ) it takes to jog 5 miles back to the park d) use your answer to parts 'a' and 'c' to write an expression that gives the total jogging time t (in hours) as a function of your average speed r(in miles per hour ) when you are jogging away from the park. write your answer as a single rational expression. e) find the total time if you jogged away from the park at an average speed (r) of 4 miles per hour. round your answer to the nearest tenth
