The middle one is proportional
If he drives 45 miles each hour, then in 'h' hours, he will cover ' 45h ' miles.
Hope this helps you out more. If you need more explaining just comment on my answer and i help you out even more deeper into the question.
The relationship between wavelength and frequency is expressed by the equation λν=c where λ is the wavelength, v is the frequency and c is the speed of light which has a value of 3x10^8 m/s.
λν=c
λ(3 × 10^9)= 3x10^8
λ = 0.1 m
Hope this answers the question.
The LCD of 1/6, 5/12, and 11 would be (12). For the denominators 6 and 12 the answer would obviously be 12 since 6 * 2 = 12 and 12 * 1 = 12 .
