1. John is a runner. He runs the 200m sprint in 15s. What speed did he travel at? (in m/s).

Explanation:

Speed = Distance traveled/ Time taken

Distance = 200m

Time = 15s

Speed = 200/15 = 13.33m/s

The answer you are looking for is approximately 13.3 m/s.

First, writing out the formula for the speed of an object, encompassing distance and time, in meters per second, or m/s,

S=D/T.  

"S" stands for "Speed."

"D" stands for "Distance."

"T" stands for "Time."

Speed (S)=

Distance (D)=200m.

Time (T)=15s.

Substituting the given values of the variables,

S=200m/15s.

200÷15=13.3333≈13.3.

So, therefore, the final answer is approximately 13.3 m/s.

*Other answers may be a little different, depending on how you round it.

I hope that this has helped answer your question. Good day to you.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
