19 Georgia runs 24 km in 10 minutes. Work out her average speed in metres per second.

## Step1:In this case, we are given that Georgia runs 2.4 km in 10 minutes and we are required to calculate her average speed in metres per second. The average speed of an object is found by dividing the total distance travelled by the total time taken. ## Step2:First, we must convert all quantities to the same units for ease of calculation. The total distance travelled is given in kilometers (km) which we need to convert into metres (m). Note: there are 1000 meters in one kilometer. We then have: As for the total time taken, it is given in minutes and we need to convert it into seconds. Note there are 60 seconds in one minute. We find: .## Step3:Once you have converted all quantities to the same units, you can proceed to calculate the average speed. ### The formula to determine speed is:### So, we have:
