A canoe can be paddled at 7 mph through a placid lake the stream flows at 3 mph

malfutka [58]

Using system of linear equations the distance at the fisherman and the bobbler meets ls 8 miles

Speed in still waters = 7 mph

Stream speed = 3 mph

Upstream speed of canoe = 7 - 3 = 4 mph

Distance between fisherman and bobbler = 14 miles

Let seperation distance = d

Meeting distance = 14 - d

using the relation :

Distance= (speed × time)

canoe distance , d = 4t - - - - (1)

Noobler distance = 14 - d = 3t ----(2)

Equate (1) and (2)

d/4 = (14 - d)/3

3d = 4 (14 - d)

3d = 56 - 4d

7d = 56

d = 8 miles

Hence, the distance is 8 miles

Answer: 3/8 of the class went to the evening session.

Explanation:

So it says on Sunday 3/4 of an 8th grade class went to see the movie.But we do not know the real population of the 8th grade class. But is says that out of the 3/4 of the students that went to the movie have of them went in the afternoon so we will multiply 1/2 by 3/4 to find out how many people went to the afternoon session.

3/4 * 1/2 = 3/8 So we know that 3/8 of the 3/4 of the class went in the afternoon so we will now subtract 3/8 from 3/4 to find out what fraction went in the evening.

$\frac{3}{4} - \frac{3}{8}$ = $\frac{6}{8} - \frac{3}{8} = \frac{3}{8}$
