4 blue = 3 white
x blue = 12 white?
Cross multiply
48 = 3x
x = 16 blue
Another way to do this is figure how many times 3 whites go into 12 whites.
That's 4 times.
So 4 blue x 4 = 16 blue
x blue = 12 white?
Cross multiply
48 = 3x
x = 16 blue
Another way to do this is figure how many times 3 whites go into 12 whites.
That's 4 times.
So 4 blue x 4 = 16 blue
Answer:
(c) 10m/s
Explanation:
to find the speed of the waves you can use the following formula:
λ: wavelength of the wave
T: period
the wavelength is the distance between crests = 48m
the period is the time of a complete oscillation of the wave. In this case you have that the float takes 2.4 s to go from its highest to the lowest point. The period will be twice that time:
T = 2(2.4s)=4.8s
by replacing you obtain:
the answer is (c) 10m/s
