Answer:
(I couldn't tell if you meant 9½ hours. So I'm just letting you know the answer I've given is if you meant 9½)
Answer = 8½ hours
Step-by-step explanation:
Speed = 40 km/h
Time = 9.5 hours
(Multiply speed by time to get distance)
40 x 9.5 = 380
New speed = 45 km/h
Distance = 380
(To calculate the time divide distance by the new speed)
380/45 = 8.5
Answer = 8½ hours
