Answer 1

Answer:

the average of whole journey is 45 km +90kph

Answer 2

Average Speed is Total Distance divided by Total Time.

Total Distance = (40km/hr x 2hr) + (60km/hr x 3hr) = 80km + 180km = 260km

Total Time = 2hrs + 3hr = 5hr

Average Speed = Total Distance / Total Time = 260km / 5hr = 52km/hr
