Answer:
Speed of sound is 340 meter per second.
Step-by-step explanation:
Let the speed of sound = x meter per second.
It is given that,
The new mode of travel has the speed 170 meter per second, which is 50% less than the speed of sound.
So, we get,
x - 50%x = 170
i.e. x - 0.5x = 170
i.e. 0.5x = 170
i.e. x = 340 meter per second
Hence, the speed of sound is 340 meter per second.
Answer:
16
Step-by-step explanation:
Let's take a look.
So we have 3*2*2*2*2=48 glasses
if half used 2 and other half used 1... we have a sum of 2+1=3
so 48/3 = 16
