Jonathon and samantha row their canoe 26 miles downstream in 2 hours. after a picnic, they row back upstream. after 3 hours they only travel 15 miles. assuming that they canoe at a constant rate and the river's current is constant, find the speed at which jonathon and samantha can row in still water.

9 mph

Step-by-step explanation:

Given

During downstream it took 2 hr to cover 26 miles

During upstream it took 3 hr to cover 15 miles

Let v be the canoe velocity and be the stream velocity

thus

------1

and

--------2

From 1 & 2 we get

2v=18

v=9 mph

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
