Travel time = Distance / Velocity
case 1: distance 215km, velocity 88.5km/h so
Travel time = 215km / 88.5 km/h = 2.429 hour
case 2: distance 215km, velocity 104.6km/h
Travel time = 215km / 104.6 km/h = 2.055 hour
So the time that can be saved is 2.429 - 2.055 = 0.374 hour

215/88.5=2.429378531 hours
215/104.6=2.055449331 hours
2.429378531-2.055449331=.373929206 hours
