With the current: Distance = 8 miles, Time = 2 hours Against the current: Distance = 6 miles, Time = 2 hours. We can use the formula: Distance = Rate × Time. For rowing with the current: 8 = (b + c) × 2. For rowing against the current: 6 = (b – c) × 2. Now we have a system of two equations: 2b + 2c = 8 2b – 2c = 6
12 lis 2015 · Using a ratio table to solve a word problem involving equivalent rates. We find the unit rate and then scale up to find equivalent rates.

Solving for rate and time. In the problem we just solved we calculated for distance, but you can use the d = rt formula to solve for rate and time too. For example, take a look at this problem: After work, Janae walked in her neighborhood for a half hour. She walked a mile-and-a-half total.
Miles per hour is calculated by knowing how long an object has been moving and how many miles it has covered in that span. Divide the number of miles travele...
Determine average velocity in miles per hour. Problem 5 : Time (A to B) = 3 hours. Time (B to C) = 5 hours. Time (C to D) = 6 hours. If the distances from A to B, B to C and C to D are equal and the speed from A to B is 70 miles per hour, find the average speed from A to D. Problem 6 : A man takes 10 hours to go to a place and come back by ...
When solving these problems, use the relationship rate (speed or velocity) times time equals distance. [latex]r\cdot t=d[/latex] 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.
