Answer:
Time taken to travel remaining 228 miles = 2.4 hours.
Explanation:
Total distance = 876 miles.
Distance traveled after speed reduction = 228 miles
So, distance traveled before = 876 - 228 =648 miles.
Time taken for this = 6 hours.
Speed before speed reduction = 648/6 = 108 mph.
Speed after speed reduction = 108 - 13 = 95 mph
Time taken to travel remaining 228 miles = 228/95 = 2.4 hours.
