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
Make customizable worksheets about constant (or average) speed, time, and distance, in PDF or html formats. You can choose the types of word problems, the number of problems, metric or customary units, the way time is expressed (hours/minutes, fractional hours, or decimal hours), and the amount of workspace for each problem.
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.
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.
How long will it be before the automobiles meet? 2. Two automobiles are 276 miles apart and start at the same time to travel toward each other. They travel at rates differing by 5 miles per hour. If they meet after 6 hours, find the rate of each. 3. Two trains travel toward each other from points which are 195 miles apart.

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 ...
