Formula Triangle

Formula Triangle

Formula Triangle can be used to find force, mass and acceleration or speed, distance and time.

Calculating Speed

• Cover the "S" for speed

• Distance and time will be calculated to determine speed

• Since distance is on top, you will divide distance by time.

• D/T = S 

•  $D\div T\equiv S$  

• Write units for speed:  km/s

• Round answer to nearest 100th

Calculate the following problem: If Edgar ran 110 meters in 12 seconds, what is his speed? (Calcular el siguiente problema: Si Edgar corrió 110 metros en 12 segundos, ¿cuál es su velocidad?)

 $D\ \div T\ =S$  

Open Ended

Determine the speed: A car traveled 240 km in 5 hours. (Determinar la velocidad: Un coche viajó 240 km en 5 horas)

 $D\ \div\ T\ =S$  

Open Ended

Determine speed: A motorcycle traveled 368 km in 8 hours. (Determinar la velocidad: Una motocicleta recorrió 368 km en 8 horas.)

Calculating Time

• Cover the “T" for time

• Distance and speed will be calculated to determine time

• Since distance is on top, you will divide distance by speed

•  $D\ \div S\ =\ T$  

• Write units for time: seconds, hours, minutes

Open Ended

Calculate time: A truck traveled 208 km at 50 km/h. (Calcular tiempo: Un camión recorrió 208 km a 50 km/h.)

 $D\ \div S=T$  

Open Ended

 $D\ \div S\ =T$  A bus travel 98 km at 49 km/h. (Un autobús recorre 98 km a 49 km/h.)

Open Ended

A motorcycle traveled 368 km at 46 km/h. (Una motocicleta recorrió 368 km a 46 km/h.)

Calculating Distance

• Cover the "D" distance

• Since Speed and Time are next to each other, you will multiply them.

• D= S x T

• Write units for distance: km, m, mi

Open Ended

Shona cycles at an average speed of 8km/h.

How far has she travelled if she cycles for 4 hours? (Shona ciclos a una velocidad media de 8 km/h. ¿Hasta dónde ha viajado si recorre 4 horas?)

Open Ended

Kelly runs from 4:50 p.m. until 5:20 p.m. at an average speed of 7km/h.

How far did she go? (Kelly funciona desde las 4:50 p.m. hasta las 5:20 p.m. a una velocidad promedio de 7 km/h. ¿Hasta dónde llegó?)
