➤Find The Relative speed of B w.r.t A. When A train moving with the speed of 30 m/s from west to east and B train moving with the speed of 48 m/s from east to west.

$\huge\frak{\underline{\underline{Answer:}}}$

$\large\bold{\boxed{\boxed{\red{78\:m/s\:east\:to\:west\:}}}}$

__________________________

$\large\bold{Explanation:}$

two railway track are parallel to west east direction

train A moves with a speed of 30 m/s from west to east

train B moves with a speed of 48 m/s from east to west

$\implies$ Relative speed of B wrt A → B - A

$\implies$30 m/s from west to east

$\implies$ - 30 m from east to west

$\implies$48 - (-30)

$\implies$ 78 m/s east to west

Hence,The Relative speed of B with respect to A is 78m/s east to west.

Answer 2

$\large{\mathbb{\red {ANSWER }}}$❤

two railway track are parallel to west east direction

train A moves with a speed of 30 m/s from west to east

train B moves with a speed of 48 m/s from east to west

\implies⟹ Relative speed of B wrt A → B - A

\implies⟹ 30 m/s from west to east

\implies⟹ - 30 m from east to west

\implies⟹ 48 - (-30)

\implies⟹ 78 m/s east to west

Hence,The Relative speed of B with respect to A is 78m/s east to west.
