Question

A train covers 14 km in 8 minutes . What is the speed of the train

Answer 1

$\fbox{ \fbox{ \bold{ \huge{Given :- \: }}}}$

$\implies \: \bold{Distance = 14 \: Km = 14 × 1000 \: Meter = 14000 \: Meter } \\ \\ \implies \: \bold{Time = 8 \: Min = 8 × 60 \: Sec \: = \: 480 \: Sec \:}$

$\fbox{ \fbox{ \bold{ \huge{To \: Find :- \: }}}}$

$\implies \: \bold{Speed = \: ? \: }$

$\fbox{ \fbox{ \bold{ \huge{Solution :- \: }}}}$

$\implies \: \bold{Speed = \frac{Distance \: }{Time \: } \: } \\ \\ \implies \bold{Speed = \: \frac{14000}{480} } \\ \\ \implies \: \bold{Speed = 29.16 \: \: \: m/s \: }$

Answer 2

$\large \bold{ \fbox{ \fbox{ \: Given \: :- }}}$

$\to \: \bold{Distance = 14 \: km \: } \\ \to \: \bold{Time = 8 \: min \: }$

$\large \bold{ \fbox{ \fbox{ \: \: To \: Find \: :- }}}$

$\to \: \: \bold{Speed = \: ?}$

$\large \bold{ \fbox{ \fbox{ \: \: Solution \: :- }}}$

$\bold{ \underline{We \: Know \: That \: , </p><p> \: \: }}$

$\large{ \bold{ \fbox{Speed = \frac{ \: Distance \: }{Time} \: }}}$

$\to \: \bold{Speed = \frac{14}{8} } \\ \\ \to \: \bold{Speed = 1.75 \: \: \: km/min}$

$\large \underline \bold{ \: Hence \: , \: Speed \: of \: the \: train \: is \: 1.75 \: \: km/min \: \: }$
