The average speed of the horse for the entire motion is 66.67 m/s.
The given parameters;
- <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
- <em>time of motion of the horse, t = 15 s</em>
The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.
The average speed of the horse is calculated as follows;

Thus, the average speed of the horse for the entire motion is 66.67 m/s.

There are 1,000m is 1k. So just move the decimal one position right. 127.56m
There are 10,000cm in 1k. Move the decimal two positions right. 1275.6cm
I cant read it, please make it focused
Hey there!:
To find the original sample population density, divide the conted colonies by the dilution factor and the inoculate:
= 73 / (10⁻⁴ * 0.1)
= 73*10⁵
Thus, the original sample's population density was 7.3*10⁶ or 73* 10⁵.
Hope this helps!
