To find the speed of the boats we will divide the distance by time.

From the graph we finde the boats' speeds as ;

Boat\quad 1\quad =\quad \frac { 35 }{ 5 } =\quad 7\quad km/h\\ \\ Boat\quad 2\quad =\quad \frac { 35 }{ 7 } =\quad 5\quad km/h

And for the speed of the third boat, we will also divide the distance by time.

Boat\quad 3\quad =\quad \frac { 32 }{ 4 } =\quad 8\quad km/h

As you can see the speed of boat 3 (8 km/h) is more than boat 1 (7 km/h) and boat 2 (5 km/h).

Thus the third boat is faster than both of them.

The answer is B.

You can see the speed of boat 1 and 2 in the picture.

angle 1 and angle 2 are complementary the measure of angle 2 is 15 degrees less than twice the measure of angle one what is the
Liula [17]
Hi there!

Let's use x as our variable. We know that complementary angles add up to 90 degrees. So, angle 1 is equal to x. Then, we can figure out that angle 2 is equal to 2x - 15. Then, to solve for x, we need to set the value of angle 1 plug angle 2 equal to 90, since the angles are complementary.

WORK:
x + 2x - 15 = 90
3x - 15 = 90
3x = 105
x = 35

ANSWER:
x = 35

Hope this helps!! :)

Since 5 is less than or equal to 5, you input it into the middle equation.

x=5

so 5 is the answer!
