Question

Kindly answer with the steps ​

Answer 1

Let the normal speed be x.

The reduced speed = x- 40 % of x

x-40x/100 = x-2x/5 = 3x/5

Let distance be d

ATQ

$\frac{d}{ \frac{3x}{5} } - \frac{d}{x} = 1$

$\frac{5d}{3x} - \frac{d}{x} = 1$

$\frac{5d - 3d}{3x} = 1$

$2d = 3x$

$d = \frac{3}{2} x$

$normal \: time \: = \frac{d}{s}$

$time = \frac{ \frac{3}{2} x}{x}$

$= \frac{3x}{2} \times \frac{1}{x} = \frac{3}{2} km \: = 1.5km$
