joe is planning a 5 hour canoe trip. he can paddle 4 miles per hour in still water and the current is 3 miles per hour. how far downstream can he go?
so his effective speed downriver is 4+3 or 7 mph
and he goes for 5 hrs
distance = rate x time
= ....
To determine how far downstream Joe can go on his canoe trip, we need to consider two factors: his speed in still water and the current.
1. Convert the given speed in still water and the current into the same unit (miles per hour).
Joe's speed in still water is 4 miles per hour, and the current is 3 miles per hour. Since he is going downstream, we need to add his speed in still water and the current together.
Joe's effective speed downstream = Joe's speed in still water + Current
= 4 miles per hour + 3 miles per hour
= 7 miles per hour
2. Multiply Joe's effective speed downstream by the duration of the trip (5 hours) to find the distance he can travel.
Distance downstream = Joe's effective speed downstream × Duration of the trip
= 7 miles per hour × 5 hours
= 35 miles
Therefore, Joe can travel 35 miles downstream on his canoe trip.
