  1. We can solve problems involving time by remembering the formula for speed, distance and time. E.g. Calculate the time if a car travels at 15 miles at a speed of 36 mph. Time = distance ÷ speed. Time = 15 ÷ 36 = 0.42 hours. 0.42 60 = 25.2 minutes. E.g. A train travels 42km between two stops at an average speed of 36 km/h.

  2. Speed and Distance. Speed is the distance you are travelling, divided by the length of time that it takes you to get there. Speed = Similarly, we can rearrange this equation as. Distance = Speed x Time . and . Time = Example. This chart describes the distance between four towns.

  3. Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.

  4. Example 1. A train leaves a station at 9:00 AM and travels with a constant speed of 90 km/h. Another train leaves the same station 10 minutes later, traveling to the same direction at the speed of 100 km/h. At what time will the second train reach the first? We will be using the formula d = vt extensively in these problems. Let’s build a chart.

  5. Example 1. Southampton, a distance of 160 miles, in 4 hours. She then drives from Southampt. n to London. 30 minutes. Determine her average speed for each journey. Solution. Plymouth to Southampton. Average speed = 160 4. Southampton to London. Time taken. = 40 mph. = 1 hour and 30 minutes. = 1 hours . or. hours. Average speed = Example 2.

  6. To find the speed of a moving object, we take the distance travelled by the object and divide it by the time it has taken to cover that distance. Thus, the formula for speed is: Speed = Distance ÷ Time. Let us see some examples to understand the concept.

  7. Draw a formula triangle for speed, distance and time. Working clockwise from the top, enter D for distance, T for time and S for speed. Use the formula triangle to work out the correct...
