You left home and traveled west at an average speed of 40 km/h. Your friend left 30 minutes later and traveled east with an average speed of 50 km/h. Find the number of hours your friend needs to travel before you are 125 km apart.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

1/800 is the right answer

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
