WebDistance, rate and time problems are a standard application of linear equations. When solving these problems, use the relationship rate (speed or velocity) times time equals distance. r⋅t = d r ⋅ t = d. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h) (4h) = 120 km.

WebTherefore, v → P S = v → P S ′ + v → S ′ S. 4.35. The velocity of a particle relative to S is equal to its velocity relative to S ′ plus the velocity of S ′ relative to S.
