27mph 64mph 185mph 1875mph 2045mph
6
Calculating speed Speed = distance ÷ time If we know the distance an object travels and the time it takes we can calculate the speed.

Recording the evidence TestDistance ( ) Time (min/s) speed m/s 1 2 3 CHALLENGE: Calculating the mean. Add up all the times ÷ the number of tests.
10
TestDistance ( ) Time (min/s) speed m/s 1 2 3 TestDistance ( ) Time (min/s) speed m/s 1 2 3
11
Considering the evidence The distance = Mean time = I walked / ran. How I calculated my speed: My speed was =
