Answer:
12 hours 52minutes and 30 seconds
Step-by-step explanation:
If the starting point is A then assume the ending point as B, now calculate - time taken for travelling from point A to point B is 8 hours 15 min., time of rest is 30 min., now see - if it took 8hr. 15min. to travel at a speed of 4 km/h so if the speed is 8 km/h it will take half the time taken to travel from point A to B which is 4hr. 7min. 30sec. .Now add all the time that is 8hr 15min. ( time taken from A to B point ) + 30min. ( rest time ) + 4hr. 7min. 30sec. ( time taken from B to A point) = 12 hours 52 minutes 30 seconds. So the answer is 33 kilometres. How it came - time takwn to travel from A to B is 8hr 15min. and speed is 4 km/h so DISTANCE = SPEED × TIME which is 4×8.25 (15 min is ¼ of 100) = 33 KM. Hope it helped you. THANKYOU
