Answer:

$\sf72 km/h$

Step-by-step explanation:

Distance covered by the train in crossing the pole = 100 m.

$\sf Time \: taken=5 \: seconds$

$\sf \: Speed \: of \: the \: train = \frac{Distance }{Time}$

$\sf = \frac{100}{5} \: m/s$

$\sf \: = 20 \: m/s$

$\sf \: = 20 \times \frac{18}{5} \: km/h$

$\sf = 72 \: km/h$

Hence, the speed of the train is 72 km/h

Solve. -1/8c=2 a. 4 b. –16 c. –4 d. 16

kotykmax [81]

$\frac{-1}{8c} =2$
This requires that c ≠ 0 , meaning c≠0
$\frac{-1}{8c} =2$
Multiply by x to eliminate var in denominator
$\frac{ \not c*(-1)}{ 8 \not c} =c*2$
$\frac{-1}{8} =c*2$
Common denominator is 8
$\frac{\not 8(-1)}{\not 8} =8c*2$
$-1=8c*2$
$-1=16c$
$x=-16$
The answer is: b. -16
