Understanding Variables in Real-World Problems

What is the dependent variable in the problem of a boat traveling downstream?

• The direction of travel

• The time taken to travel

• The distance traveled

• The speed of the boat

Which variable affects the time it takes for the boat to travel downstream?

• The type of water

• The color of the boat

• The speed of the boat

• The weight of the boat

What is the equation used to find the total distance traveled by the boat?

• X * Y = 105

• X / Y = 105

• X - Y = 105

• X + Y = 105

If the boat travels at 20 mph, how long will it take to cover 105 miles?

• 5 hours

• 7 hours

• 3.5 hours

• 10 hours

How does changing the speed of the boat affect the time taken to travel the distance?

• It changes the direction of travel

• It changes the time taken

• It does not affect the time

• It increases the distance
