What is the formula for speed?
Speed = Distance/time
Distance = meters
Time = seconds
Speed = meters per second
A hooligan sheep is skateboarding down a farmer’s track. You notice it takes exactly 5 seconds to move between two fence posts, 10 metres apart. What is the sheep’s speed?
Because we know that distance over time is speed, then we have to do 10÷5 = 2 and that means that our answer is 2 m/s.
A campervan trundles down the road, travelling 15 miles in 30 minutes. What is it’s Speed in miles per hour?
Because we know that distance over time equals speed and the distance is 15 miles and the time is 30 minutes then we do 15÷0.5 which equals 30 miles per hour.
