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.
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. So to keep the information in the problem organized, use a table. An example of the basic structure of the table is below:
Divide the number of miles traveled by the hours spent traveling to calculate miles per hour with help from a math teacher in this free video on basic math lessons. Expert: Jimmy Chang...
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.
Distance Word Problems. Whenever you read a problem that involves "how fast", "how far", or "for how long", you should think of the distance equation, d = rt, where d stands for distance, r stands for the (constant or average) rate of speed, and t stands for time. Make sure that the units for time and distance agree with the units for the rate.
