Question

impulses in nerve fibers travel 285km in 2.3 hours. what is the rate, or speed, in km per hr?round to the nearest integer.

Answer 1

Remember, you can multiply any number 1 without changing it, and that 1000m/1km = 1

Answer 2

Distance=SpeedxTime.
We need to calculate speed so we divide the distance by the time it takes to travel that much distance. so we get 285/2.3=123.91304 which to the nearest integer will be 124 km/h

Answer 3
