Train Speed and Distance Quiz

What is the main question posed in the train problem?

• How far will the faster train travel?

• When will the slower train stop?

• What is the speed of the slower train?

• When will the faster train catch up to the slower train?

What is another term used for speed in the context of this problem?

• Distance

• Velocity

• Time

• Rate

Which formula is used to solve the train problem?

• Rate = Distance x Time

• Distance = Rate x Time

• Distance = Time / Rate

• Time = Distance x Rate

Why is it important to be aware of the units of measure in this problem?

• To find the weight of the trains

• To determine the color of the trains

• To correctly calculate the distance

• To ensure the trains are on the same track

What variable is used to represent the time it takes for the faster train to catch up?

• r

• v

• d

• t

How is the time for the slower train expressed in the equation?

• t - 1

• 2t

• t + 1

• t

What is the first step in solving the algebraic equation for the train problem?

• Subtract 60 from both sides

• Add 90t to both sides

• Multiply both sides by 2

• Subtract 90t from both sides

What is the final step to solve for t in the equation?

• Multiply both sides by 60

• Divide both sides by 30

• Add 30 to both sides

• Subtract 60 from both sides

What is the correct answer for the time it takes for the faster train to catch up?

• 3 hours

• 4 hours

• 2 hours

• 1 hour

What is the significance of the units of measure in the final answer?

• They ensure the time is in hours

• They confirm the distance is in miles

• They indicate the train's weight

• They determine the train's color
