Final answer:
To determine the travel time for 570 km at the same average speed used for a 380 km trip over 4 hours (95 km/h), divide the new distance by the average speed, resulting in a travel time of 6 hours.
Step-by-step explanation:
To find out how long it will take to travel 570 km at the same average speed, we first need to calculate the average speed during the initial 380 km trip. We do this by dividing the distance by the time it took to travel that distance. Using the information given:
Average speed = Distance / Time = 380 km / 4 h = 95 km/h.
Now, to find out how long it will take to travel 570 km at this average speed, we divide the new distance by the average speed:
Time = Distance / Average speed = 570 km / 95 km/h.
Therefore, it will take 6 hours to travel 570 km at the same average speed. It's always important to check whether the answer is reasonable by comparing it with the information given in the problem.
