Creative Speed Calculation with Khan
Why did Khan multiply 20 miles per hour/second by 1/3600?
Can you explain the reason behind this calculation?
Answer:
In this context, the number 3600 is used to convert the time unit from hours to seconds in speed calculations. It is an essential step to ensure the correct unit of measurement is used.
Khan multiplied 20 miles per hour/second by 1/3600 in order to convert the speed from miles per hour to miles per second. By multiplying by 1/3600, he effectively changed the time unit from hours to seconds.
Speed is calculated by dividing the distance traveled by the time taken. In this case, Khan needed to convert the time unit to seconds to match the speed unit in miles per second.
Therefore, the multiplication by 1/3600 helped Khan adjust the time unit, ensuring the accuracy of the speed calculation.
