Question

A train is moving at a constant speed. If the train covers 50km in 2 hours, how much time would it take to cover 100km ?

Answer 1

$\huge\bf{Answer:-}$

Speed = 50km / 2 hr

Time = 2 hr

Formula:

Distance = Speed / Time

= 50 / 2 = 25 h-¹

= 100 / 25 h-¹ = 4

Therefore, 4 is the time taken to cover 100km.

Answer 2

$\huge{\underline{\underline{\boxed{\mathfrak{\red{Hi \:Dear}}}}}}$

$\large{\underline{\mathfrak{\red{Solution:}}}}$

Given,

Distance travelled in $2h \:= \:50km$

$Speed \:= \:\frac{Distance}{Time}$

$>> \:Speed \:= \:\frac{50}{2} \:= \:25km \:h^{-1}$

Now, to travel 100km at the same speed as given above,

$Speed \:= \:25km \:h^{-1} \:= \:\frac{Distance}{Time}$

$>> \:Time \:= \:\frac{100km}{25km \:h^{-1}}$

$>> \:Time \:= \:\frac{100}{25} \:= \:4h$

$\large{\underline{\underline{\boxed{\boxed{4h}}}}}$
