Question 159534: A family makes a 43.25 km trip in 5.5 hours. On the first part of the trip they crossed a lake in a canoe paddling at 12km/h. For the rest of the trip,they hiked on a scenic trail. If their average walking speed was 5km/h how far did they walk?

Remember: ---> , BASIC EQN
, canoe paddling
, hike in scenic trail (walking)
Other points to remember: ,
In BASIC EQN we get, , working eqn
Also, . Make sense, time in canoe paddling + time hiking = total time in the trip.
Then as per working eqn,
----------------> eqn 1
But remember too, distance in canoe paddling + distance in hiking = total distance in trip ---> ,subst, in eqn 1

, cross multiply

--------------------> distance travelled in walking
-----------> distance travelled in canoe paddling
In doubt? Go back eqn 1,

Thank you,
Jojo
