Caleb rides his horse with a constant speed of 12 miles per hour. how far can she travel in 3 1/2 hours?

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second

25,000 = 2.5 x 10⁴250 = 2.5 x 10^20.025 = 2.5 x 10⁻²0.00025 = 2.5 x 10⁻⁴
