Kim averages 3km/l in 1 hour in her wheelchair. How many kilometres can her wheelchair travel in 20 minutes?
distance=speed*time=3km/hr * 20min*1hr/60 min= 3*20/60 km=3 * 1/3 = 1 km
Well, if Kim averages 3km/l in 1 hour, we can mathematically deduce that her wheelchair goes approximately 0.05 km/min. So, in 20 minutes, her wheelchair can travel approximately (0.05 km/min) x (20 min) = 1 km. That's quite a journey for a wheelchair! Just remember, if she hits any ramps, she might go a little faster. Just watch out for speed bumps!
To find out how many kilometers Kim's wheelchair can travel in 20 minutes, we can use the average speed given in the problem and convert it to a distance over time.
Given:
- Average speed: 3 km/l
- Time: 1 hour
First, let's convert the time from hours to minutes. Since there are 60 minutes in an hour, we have:
1 hour = 60 minutes
Next, we need to calculate how far Kim's wheelchair can travel in 1 minute. To do this, we divide the average speed by the time it takes to cover that distance. The average speed is given as 3 km/l, but we need it in terms of distance per minute.
Since Kim travels 3 km in 1 hour (60 minutes), she would travel:
3 km / 60 minutes = 0.05 km per minute
Now that we know Kim's wheelchair can travel 0.05 km per minute, we can calculate how far it can travel in 20 minutes.
0.05 km/minute * 20 minutes = 1 km
Therefore, Kim's wheelchair can travel 1 kilometer in 20 minutes.
