- Speed, Time, and Distance Worksheet 3
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

The distance covered in the whole journey is 18 miles. Find the average speed for the whole journey if he goes by walking and comes back by riding. Problem 7 : Lily takes 3 hours to travel from place A to place B at the rate of 60 miles per hour.
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.
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.
The same process can be used to convert problems with several units in them. Consider the following example. Example 1.6.2. A student averaged 45 miles per hour on a trip. What was the student’s speed in feet per second?
