A student practicing for a cross country meet runs 250m in 30s. what is her average speed?

If you're looking for an answer in m/s then 8.33.. ms^-1

Explanation:

To determine average speed then we simply need to divide the total distance travelled by the total time it took to travel that distance.

I.e. 250/30=8.33m/s

To convert this to km/h we simply need to multiply the answer in m/s by 3.6 which gives us approximately 30km/h

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
