Ko Sheen took a total of 10 minutes to jog 5 rounds. Each round was 0.4 km. Find her average speed for the 5 rounds. Ans: ___ m / min

1. Convert the distance of one round from km to meters

$0.4 \text{ km} = 0.4 \times 1000 \text{ m} = 400 \text{ m}$

2. Calculate the total distance jogged

$\text{Total distance} = 5 \times 400 \text{ m} = 2000 \text{ m}$

3. Calculate the average speed in m/min

$\text{Average speed} = \frac{2000 \text{ m}}{10 \text{ min}} = 200 \text{ m/min}$
