Answer: The lorry is traveling 10 mph over the expected speed.
Step-by-step explanation:
If 200 miles takes 4 hours, the speed is 200mi/4hr which is 50 mph.
If the distance is increased by 20%, the distance is 240 miles.
240mi/4hr = 60mph
The difference is 10mph
Divide 1681 by 4 which is about 420.25 feet for length
