Kaya drove 200 miles in 5 hours of actual driving time. By driving an average of 10 miles per hour faster, Kaya could have saved how many hours of actual driving time? Hmm..?

40mi/hr so if it was 10 mi/hr faster that would be 50mi/hr so I just divide that by 200 and get 4...so does that mean he saved 1 hour? Is that right?
