Roger Waters can scrape up just enough money to rent a canoe for 1 hour and 30 minutes. If he paddles out on a lake at 4 kph and returns at 2 kph, how far will he have paddled the canoe? Show work and table.

If he is continuing paddling then, d = r. tHe has to paddle the same distance back to shore,

4t1 = 2t2

t2 = 2t1

The taken to him is the twice he reaches to the dest. off the shoret1 + t2 = 1.5

Putting the values we get

t1 + 2t1 = 1.53t1 = 1.5

t1 = 0.5t2 = 1

d = 4*0.5

= 2*1

= 2
