A train 575 m long crosses a tunnel of length 325in 90 sec. what is the speed of the train in kmph

________________________________

step by step explanation:

According to question

• what is speed of the train in kmph?

______________________________

Now,

$\sf{total \: distance \: travell = length \: of \: train + length \: of \: tunnel}$

• length of train is 575
• length of tunnel is 325

Given from the question

$\tt{ = 575 + 325 = 90}$

Time taken tunnel is 90 second

Do u know formula,

$\rm{speed = \frac{distance}{time} \times \frac{18}{5}}$

$\rm{ = \frac{900}{90} \times \frac{18}{5}}$

$\rm{ = \frac{180}{5}}$

$\rm{ = 36kmph}$

I hope it's help uh
