First, we need to convert the distance from meters to miles:
200 meters = 0.124 miles

Next, we need to convert the time from seconds to hours:
19.98 seconds = 0.00555 hours

Finally, we can divide distance by time to find the speed in miles per hour:
Speed = Distance / Time
Speed = 0.124 miles / 0.00555 hours
Speed = 22.39 miles/hour, which rounded to the nearest tenth is 22.4 miles/hour.

Therefore, the best choice is (B) 22.4 miles/hour.
