On a steeper slope, the jogger can run at an average speed of 5.3 miles per hour up the slope and 6.7 miles per hour going down the slope. how long, in hours, the full trip will take (1 mile uphill and 1 mile downhill). give an exact answer expressed as a fraction in simplest terms and then give a decimal approximation correct to three decimal places. (hint: use the same method as in #1.) reduced fraction: decimal approximation:
