A boat travels upstream for 48 miles in 3 hours and returns in 2 hours traveling downstream in a river. What is the rate of the

alekssr [168]

Answer:

20 mph and 4 mph

Step-by-step explanation:

GIVEN: A boat travels upstream for $48$ miles in $3$ hours and returns in $2$ hours traveling downstream in a river.

TO FIND: What is the rate of the boat in still water and the rate of the current.

SOLUTION:

Let the speed of boat in still water be $s$ and speed of current be $a$ .

$\therefore$ speed of water in upstream $=s+a$

speed of water in downstream $=s-a$

As $speed=\frac{distance}{time}$

$s+a=\frac{48}{3}=16$

$s-a=\frac{48}{2}=24$

Solving both we get

$s=20\text{ mph}$

$a=4\text{ mph}$

Hence speed of boat in still water and rate of current is 20mph and 4mph respectively.

Given A = 1/2(b1 + b2)h, solve for h.

sp2606 [1]

The answer is h = 2A/(b1 + b2).

In order to find this, use all the methods for solving typically used in these types of equations. See the below example.

A = 1/2(b1 + b2)h ---> Multiply both sides by 2.

2A = (b1 + b2)h -----> Divide both sides by (b1 + b2)

2A/(b1 + b2) = h
