If the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.
<h3>How to convert speed?</h3>
The speed of a car is the measure of the distance moved over a given period of time, hence, it is measured in miles/hour, km/hr, m/s etc.
According to this question, the speedometer in a car reads 78 miles per hour.
Since the conversion factor of kilometers per hour and miles per hour is as follows:
1 kilometer per hour = 0.62 miles per hour
Then, 78 miles per hour = 125.53 kilometers per hour.
Therefore, if the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.

The isotopes are elements with the same number of protons but different number of neutrons.
Boron atomic number is 5. That is the number of protons.
The natural occurring isotopes of boron contain 5 or 6 neutrons. Other, non stable isotopes, contain from 1 to 16 neutrons.
