how to do speed distance time calculations
Answer. Speed = distance Ã· time. Speed = 70 Ã· 2 = 35 km/h. The distance in km and the time in h, so the units for speed are km/h. If you know the speed, you can work out the time or the distance by re-arranging the equation.speed = distance Ã· time.peed = 70 Ã· 2 = 35 km/h. The distance in km and the time in h, so the units for speed are km/h. If you know the speed, you can work out the time or the distance by re-arranging the equation. speed = distance Ã· time.
All of the calculations in this section will be worked out using the distance, speed and time equation. An easy way to remember the distance, speed and time equations is to put the letters into a triangle.The triangles will help you remember these 3 rules: 1  Distance = Speed x Time.n the next page there are some examples to work through. Have paper and a pen handy, draw the distance, speed and time triangle on your paper, then try the examples. It might be helpful to first take a look at Bitesize Time Calculations.
