How to Find Each Choreographer's Rate
Gene's Rate
- d = rt
- 1 = r * 5
- 1 ÷ 5 = r * 5 ÷ 5
- 1/5 = r
Michael's Rate
- d = rt
- 1 = r * 4
- 1 ÷ 4 =r * 4 ÷ 4
- 1/4 = r
Janet's Rate
- d = rt
- 1= r * 10
- 1 ÷ 10 = r * 10 ÷ 10
- 1/10 = r
What do you know?
- 1 = Gene's rate * t + Michael's rate * t + Janet's rate * t
- 1= (1/5)t + (1/4)t + (1/10)t
Solve for t:
- 1= (1/5)t + (1/4)t + (1/10)t
- 1= (11/20) * t
- 1÷ (11/20) = (11/20) * t ÷ (11/20)
- 20/11 = t
