V = s/t
now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t
and
340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195
Answer is 195mph
Yes 16/12 divided by 4 by the numerator and denominator is 4/3
I am guessing right now, but here it is
x=6x+x-2x
Answer:
109.9?
Step-by-step explanation:
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.
