Question

A boat travels at a constant speed for 3 hours it travels 195.0 six kilometers what is its speed.

Answer 1

Hi Melissa,

 

When something is traveling at a constant speed for several hours, say a car going 50 miles per hour and traveling for 3 hours, you would simply add the distance traveled each hour to get the total distance traveled.

 

This would be: 50 miles + 50 miles + 50 miles = 150 miles (50 miles for each hour traveled)

A simpler way to think about this would be 50 miles * 3 = 150 miles.

 

And so we can always think of the idea: SPEED x TIME = DISTANCE

 

Now to do it the opposite, knowing the distance and wishing to find out the speed, we would simply divide instead of multiply: SPEED = DISTANCE / TIME (we divided both sides by TIME from the line before)

 

In your case: 195 / 3 = 65

So 65 kilometers / hour
