A plane flies 50km in 15 minutes. How long does it take to fly 300km?
To find the time it takes to fly 300km, we can set up a proportion:
50km/15 minutes = 300km/x minutes
Cross-multiplying, we get:
50x = 15 * 300
50x = 4500
Dividing both sides by 50:
x = 4500/50
Simplifying, we get:
x = 90
Therefore, it takes 90 minutes to fly 300km.
To find out how long it takes to fly 300km, we can use the concept of proportionality. We know that the plane flies 50km in 15 minutes, so we can set up a proportion to solve for the time it takes to fly 300km.
Let's set up the proportion:
50km / 15 minutes = 300km / x
To solve for x (the time it takes to fly 300km), we cross-multiply and solve for x:
50 * x = 15 * 300
x = (15 * 300) / 50
x = 90
Therefore, it would take the plane 90 minutes to fly 300km.
To find out how long it takes for the plane to fly 300 km, we can set up a proportion using the given information.
Let x represent the unknown time it takes for the plane to fly 300 km.
We know that the plane flies 50 km in 15 minutes. So, we can set up the following proportion:
50 km / 15 min = 300 km / x
To solve for x, we can cross-multiply the proportion:
50 km * x = 15 min * 300 km
Now, we need to solve for x.
Divide both sides of the equation by 50 km:
x = (15 min * 300 km) / 50 km
Simplifying this expression, we get:
x = (15 * 300) / 50
x = 900 / 50
x = 18
Therefore, it takes 18 minutes for the plane to fly 300 km.
