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.

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

Back

Speed (R) can be calculated by rearranging the formula to R = D/T, where D is distance and T is time.

If a bat flies for 400 seconds and covers 100 meters, how do you find its speed?

Back

Speed = Distance / Time = 100 m / 400 s = 0.25 m/s.

If Joanna drives 400 km at an average speed of 80 km/h, how long does her journey take?

Back

Time = Distance / Speed = 400 km / 80 km/h = 5 hours.

Front

What is the combined speed of two objects moving towards each other?

Back

The combined speed is the sum of their individual speeds.

Front

If a Mustang travels at 82 mph and a Corvette at 65 mph, how do you find the time until they meet?

Back

Time = Distance / (Speed of Mustang + Speed of Corvette).

If a ball rolls down a hill for 500 m in 1 minute and then 300 m in 3 minutes, how do you find its average speed?

Back

Total Distance = 500 m + 300 m = 800 m; Total Time = 1 min + 3 min = 4 min; Average Speed = 800 m / 4 min = 200 m/min.

If a man runs at a speed of 70 m/s for 30 seconds, how do you find the distance he ran?

Back

Distance = Speed x Time = 70 m/s x 30 s = 2100 m.
