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

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.
The formula for distance problems is: distance = rate × time or. d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
