8. Jess walked for 45 minutes at 3 km/h and then ran for half an hour at x km/h. At the end
Law Incorporation [45]

<u>Answer:</u>

x = 7.5 km/h

<u>Step-by-step explanation:</u>

• First calculate the distance covered by walking at 3 km/h for 45 minutes ( 0.75 h):

distance = speed × time

              = 3 × 0.75

              = 2.25 km

• Therefore, she covered 2.25 km of the total journey by walking. Since she was 6 km from the starting point at the end of the entire journey, we can calculate the distance remaining, which she had to run:

distance she had to run = 6 - 2.25

                                        = 3.75 km

• Now we can calculate the speed of the 30 minute (0.5 h) run:

speed = distance ÷ time

           = 3.75 ÷ 0.5

           = 7.5 km/h    

This means that she ran at 7.5 km/h for half an hour.

∴ x = 7.5

Need help with this problem
velikii [3]
Let the horizontal distance is x and vertical distance is y and the distance  between them is z  
z^2 = x^2 + y^2  
2z(dz/dt) = 2x(dx/dt) + 2y(dy/dt)               divide by 2
z(dz/dt) = x(dx/dt) + y(dy/dt)
when y = 45 , x = 0 because the boy was under the balloon 
after 3 secs: x = 15 * 3 = 45 , y = 5 * 3 = 15 , z = sqr(x^2 +y^2) = 75 
z(dz/dt) = x(dx/dt) + y(dy/dt)
75(dz/dt) = 45(15) + 15(5) = 975
dz/dt = 13 ft/sec
