D=RT

Front

What does the formula D=RT represent?

Back

D=RT represents the relationship between Distance (D), Rate (R), and Time (T). It states that Distance equals Rate multiplied by Time.

Front

If a car travels at a speed of 60 miles per hour for 2 hours, how far does it travel?

Back

120 miles (Distance = Rate x Time = 60 mph x 2 hours).

Front

What is the average speed of an object?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you calculate time using the formula D=RT?

Back

Time (T) can be calculated by rearranging the formula to T = D/R.

Front

If two objects are moving towards each other, how do you find the time until they meet?

Back

Add their speeds together to find the combined speed, then use the formula T = D/(R1 + R2) where D is the distance between them.

Front

What is the unit of speed in the formula D=RT?

Back

Speed can be measured in units such as miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s).

Front

If a runner completes a 10 km race in 50 minutes, what is their average speed?

Back

12 km/h (Average speed = Total distance / Total time = 10 km / (50/60) hours).

Front

What is the relationship between speed, distance, and time?

Back

Speed is directly proportional to distance and inversely proportional to time.

Front

If a cyclist travels 30 miles in 1.5 hours, what is their speed?

Back

20 mph (Speed = Distance / Time = 30 miles / 1.5 hours).

Front

How do you convert hours to minutes?

Back

Multiply the number of hours by 60 (1 hour = 60 minutes).
