Measuring Distance

The video tutorial explains the concept of formulas, focusing on the distance formula: distance equals rate times time (d = r * t). It provides an example with Sasha driving at 50 miles per hour for 4 hours, calculating the distance traveled as 200 miles. The tutorial also addresses unit conversion, showing how to convert 30 minutes into 0.5 hours to calculate the remaining distance Sasha needs to travel. The lesson concludes by reinforcing the importance of consistent units in calculations.

What is the formula used to calculate distance in terms of rate and time?

• d = r + t

• d = r / t

• d = r - t

• d = r * t

If a car travels at a speed of 50 miles per hour for 4 hours, how far does it travel?

• 200 miles

• 250 miles

• 150 miles

• 100 miles

In the example, what is the rate at which Sasha is driving?

• 70 miles per hour

• 40 miles per hour

• 50 miles per hour

• 60 miles per hour

How should 30 minutes be converted to match the time unit in the rate of 50 miles per hour?

• 0.7 hours

• 0.3 hours

• 0.5 hours

• 0.6 hours

After converting 30 minutes to hours, how much farther does Sasha need to drive?

• 20 miles

• 15 miles

• 30 miles

• 25 miles
