Given:
mb=2.05 kgmb=2.05 kg Mass of the book
fs=2.45 Nfs=2.45 N Static friction
fk=1.50 Nfk=1.50 N Kinetic friction
Answer:
Explanation:
Time = (distance) / (average speed)
Time = (4,700 km) / (790 km/hr) = 5.9494 hours (rounded)
= 5hrs 56min 58 sec (rounded)
(4,700 km) / (1.609344 km/mile) = 2,920 miles
Speed = (distance covered) / (time to cover the distance)
(2,929 miles) / 5.9494 hours) = 491 miles per hour

She should have done observation first before asking a question and forming a hypothesis. </span>
