You guys came to the exact same with detailed research, Oscar through whatever means he used (perhaps just estimating??) way back when!
If the ball did not lose speed, a forehand hit at 80mph (~120 feet per second), would take 0.67 seconds to travel 80 feet to the opposite baseline.

But players know that they have much more than 0.67 seconds (>1.0 second) to react.

Players 100 years ago would have intuitively known the ball significantly slows down during its flight..
