Now let’s generalize. a. running uphill the jogger runs c mph slower than 6 mph. write an expression representing a speed of c mph slower than 6 mph.
b. write an algebraic expression that represents the time it takes to run 1 mile uphill at a speed that is c mph slower than 6 mph. (refer to #1a for .)
c. running downhill the jogger runs c mph faster than 6 mph. write an expression represents a speed of c mph faster than 6 mph.
d. write an algebraic expression that represents the time it takes to run 1 mile downhill at a speed that is c mph faster than 6 mph. (refer to #1b for .)
e. use your answers to b and d to write an algebraic expression for the total time, in hours, that it takes the jogger to cover 2 miles by going uphill for 1 mile and then returning 1 mile back down the hill.
f. simplify your answer to part e into a single algebraic fraction. (remember to find a common denominator first.)
g. what is the value of c for #1? (how much slower does she run uphill? ) use this c to test your answer to part f. (check that it gives the correct answer for #1c.)
h. what is the value of c for #2? (how much slower does she run uphill? ) use this c to test your answer to part f. (check that it gives the correct answer for #2.)
