Jane and sali cycled along the same 63 km route.

Alina [70]

Answer:

Sali's speed was 18.75 km/h.

Step-by-step explanation:

Jane took 3.5 hours to cycle the 63 km.

As, $Speed= \frac{Distance}{Time}$ , so the speed of Jane will be: $\frac{63}{3.5} km/h = 18 km/h$

Suppose, the speed of Sali is $x$ km/h

Sali caught up with Jane when they had both cycled 30 km.

So, the time required for Jane to cycle 30 km $= \frac{30}{18}=\frac{5}{3} hours$ and the time required for Sali to cycle 30 km $=\frac{30}{x} hours$

Given that, Sali started to cycle 4 minutes or $(\frac{4}{60}) or (\frac{1}{15}) hours$ after Jane started to cycle. So, the equation will be.......

$\frac{5}{3}-\frac{30}{x}= \frac{1}{15}\\ \\ \frac{30}{x}= \frac{5}{3}-\frac{1}{15}\\ \\ \frac{30}{x}= \frac{24}{15}\\ \\ 24x=450\\ \\ x= \frac{450}{24}= 18.75$

Thus, the speed of Sali was 18.75 km/h.

What are the coordinates of the points (2,-3) after a counter clockwise rotation of 90 about the Origin?

Ber [7]

Step-by-step explanation:

(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.

Any point in the 1st quadrant has both positive x and y coordinates.

So the answer is (3, 2).

triple one number added to another number is 22. if the second number is equal to 8 less than 2 times the first number, find the

Scrat [10]

Answer:

6 and 4

Step-by-step explanation:

Let the numbers are x and y.

Given:

3x + y = 22
y = 2x - 8

Solve by substitution:

3x + 2x - 8 = 22
5x = 22 + 8
5x = 30
x = 6

Find y:

y = 2*6 - 8 = 12 - 8 = 4
