An airplane moving a speed of 300 miles per hour for 10 hours traveled how far?

Question

plz help me i dont wont to fail

Answer 1

Grant,

If something goes a certain number of miles per hour, that means that every hour, they go that distance.  Your plane is going 300 miles every hour.  So in 1 hour, the plane goes 300 miles.  In 2 hours, it goes 300 more, or 600 miles.  For every mile, you would add another 300 miles.

The short way to do repeated addition is to multiply.  In 4 hours, the plane will go 4 * 300 = 1200 miles.  In 7 hours, 7 * 300 = 2100 miles.  How many miles in 10 hours?

You can take it from here.

Answer 2

Really?  You know the rate, namely 300 miles per hour.

How far does it go at that rate in 1 hour?

in two hours?

...

in ten hours?

 

In conclusion, I give you one word of advice: MULTIPLY; I hope that you see why.
