WebWhen 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. The problems to be solved here will have a few more steps than described above. WebThe equation to solve is: 1 R + 1 2R = 1 10 h, where Doug's rate ( 1 D) = 1 2 × Becky's ( 1 R) rate. Sum the rates: 1 R + 1 2R = 2 2R + 1 2R = 3 2R Solve for R: 3 2R = 1 10 h which means 1 R = 1 10 × 2 3 h so 1 R = 2 30 or R = 30 2 1 R + 1 2 R = 1 10 h, where Doug's rate ( 1 D) = 1 2 × Becky's ( 1 R) rate.
