A train 100 m long crosses a pole in 5 seconds.Find the speed of the train in kilometre per hour.

In-s [12.5K]

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 for p: p - 6 = 5* p = 1 p = 11 p = -1

julsineya [31]

Step-by-step explanation:

$\text{p - 6 = 5}$

Since we want to get ' p ' on left hand side , remove the number ' - 6 '.

⇢ $\text{p - 6 + 6 = 5 + 6}$ { The opposite of -6 is +6 and whatever we do to one side , we must do to the another side. So, I added 6 on both sides }

⇢ $\text{p = 11}$ { On the left hand side , 6-6 = 0. That's how we removed the 6 so just 'p' is left. On the right hand side , 5+6 = 11 }

---------

$\underline{ \underline{ \text{CHECK }}} :$

Always check your answer by substituting your answer for the variable that you solved for. This guarantees you a right answer !

$\text{p - 6 = 5}$

⇢ $\text{11 - 6 = 5}$

⇢ $\text{5 = 5}$

$\pink{ \underline{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{p = 11}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ
