Assume the problem is:
The distance from here to the beach at Little Boar's head is 10miles.
If you walked there at 4mph and returned jogging at 8mph, how much time would the round trip take?
:
Let t = time for round trip
:
Write a time equation: time = dist/speed
:
total time = walk time + jog time
t = +
reduce fraction
t = +
t =
t = 3.75 hrs
:
" What would your overall average speed be?"
Total dist = 20 mi
Speed = dist/time
S =
S = 5 mph
