Chad jogs 4 2\5 miles in 1\2 hour. What is his average speed in miles per hour?
Never Say Die!
22 miles per hour?
An hour is 2 times 1/2 hour, therefore the speed in miles per hour = 4.4 * 2 = ? miles per hour
To find Chad's average speed in miles per hour, we need to divide the distance he covered by the time it took him.
Chad jogged 4 2/5 miles in 1/2 hour.
To convert the mixed number 4 2/5 into an improper fraction, we multiply the whole number by the denominator and add the numerator:
4 * 5 + 2 = 22
The improper fraction equivalent of 4 2/5 is 22/5 miles.
Now we can calculate Chad's average speed in miles per hour:
Average speed = Distance / Time
Distance = 22/5 miles
Time = 1/2 hour
Average speed = (22/5) / (1/2)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
Average speed = (22/5) * (2/1)
Multiplying the numerators together and the denominators together:
Average speed = (22 * 2) / (5 * 1)
Average speed = 44/5
Therefore, Chad's average speed is 44/5 miles per hour.
