# Kenneth drove 194.3 miles in 3 7/20 hours. What was his average speed?

58 miles per hour

In this case average means; what is the one value that if multiplied by the total time (in hours) will give 194.3 miles.

We do this by ending up with the distance traveled in 1 hour (unit time)

To find Kenneth's average speed, divide the total distance traveled by the total time taken:

Average speed = Total distance / Total time

Total distance = 194.3 miles Total time = 3 7/20 hours

Convert the mixed number time to an improper fraction: 3 7/20 hours = (3 * 20 + 7)/20 = (60 + 7)/20 = 67/20 hours

Average speed = 194.3 miles / (67/20) hours

Divide the total distance by the total time: Average speed = 194.3 miles / (67/20) hours

To divide by a fraction, multiply by its reciprocal: Average speed = 194.3 miles * (20/67) hours

Calculate the result: Average speed ≈ 57.94 miles/hour
