Calculating Average Speed: Mary's 10km Run in 40 Minutes Explained

Thread starter almost__overnow
Start date Aug 31, 2006

AI Thread Summary

Mary's average speed for her 10-kilometer run can be calculated by converting the distance into meters and the time into seconds. A kilometer is equal to 1,000 meters, so 10 kilometers is 10,000 meters. Forty minutes is equivalent to 2,400 seconds. To find the average speed, divide the total distance by the total time, resulting in an average speed of approximately 4.17 meters per second. Understanding the relationships between kilometers and meters, as well as minutes and seconds, is essential for calculating speed accurately.

Mary runs 10 kilometers in 40 minutes. What is her average speed in meters per second?

i don't understand and its only like the 4th day of school.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
