Reece is given a lift to school. She leaves the house at 8:30 am and arrives at school at 8:50 am. She uses an app on her phone to calculate her average speed for the journey. Her phone displays 6.8m/s What distance did she travel? Give your answer to 2 significant figures.

## Step 1:First, we need to calculate the total time Reece spent on her journey. She left the house at 8:30 am and arrived at school at 8:50 am. This means she spent 20 minutes on the journey.## Step 2:We need to convert this time from minutes to seconds because the speed given is in meters per second (m/s). We know that 1 minute is equal to 60 seconds. Therefore, 20 minutes is equal to seconds.## Step 3:Now, we can calculate the distance she travelled using the formula for distance which is speed multiplied by time. Her speed was and the time was 1200 seconds.### The formula for distance is: ### ## Step 4:Substituting the given values into the formula, we get: ### ## Step 5:Perform the multiplication to find the distance.
