I was on one side of the earth and i ran to the other side which took me 20 seconds. How fast was i going in MPH?
To calculate your speed in miles per hour (MPH), we need to know the distance you traveled. The Earth's circumference is approximately 24,901 miles. If you ran from one side of the Earth to the other, you would have covered half of the Earth's circumference, which is about 12,450.5 miles.
You mentioned that it took you 20 seconds to cover this distance. To find your speed in MPH, we can use the formula:
[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} ]
First, convert the time from seconds to hours:
[ 20 \text{ seconds} = \frac{20}{3600} \text{ hours} = \frac{1}{180} \text{ hours} ]
Now, calculate the speed:
[ \text{Speed} = \frac{12,450.5 \text{ miles}}{\frac{1}{180} \text{ hours}} = 12,450.5 \times 180 \text{ MPH} = 2,241,090 \text{ MPH} ]
So, you would have been traveling at approximately 2,241,090 miles per hour.
