Heya!!

Here's your answer !!

Average speed is 55 km/h, combined time is 5 hours,

combined distance is 275 km.

• 2 hours × speed is 60 km/h, Time is 2 hours, distance is 120km.

• 2 hours × speed is 50 km/h, Time is 2 hours, distance is 100km.

Combined distance is 220 km, time is 4 hours, average speed is 55 km/h is for above times only and does not include 5th hour.
