Question

Find our the total distance between those 2 womens after 100 seconds. Refer the image for the full question ASAP. Give me a complete brief solution of this above question!​

Answer 1

Given

$\small\bf\red{First\: Women}\begin{cases}\sf{Initial\: Velocity\: =\: 15m/s}\\\sf{Time\: Taken\: = 100\: seconds}\end{cases}$

$\small\bf\green{Second\: Women}\begin{cases}\sf{Initial\: Velocity\: =\: 20m/s}\\\sf{Time\: Taken\: = 100\: seconds}\end{cases}$

To Find

$\:\:\:\:\bullet\:\:\sf{Distance \: between \:them \:after \:{\sf{\blue{100 \:seconds}}}}$

Solution

$\\→\:\:\:\sf Distance\: travelled \:by \:1st \:women\: = \: Velocity \times Time\:taken$

$→\:\:\:\sf 15 \times 100$

$→\:\;\:\sf 1500m$

$→\:\:\:\sf s_{1} = {\sf{\red{1500m}}}$

$\Rightarrow\:\:\:\sf Distance \:travelled \:by\: 2nd \:women\: = \: Velocity \times Time\:taken$

$\Rightarrow\:\:\:\sf 20 \times 100$

$\Rightarrow\:\:\:\sf 2000m$

$\Rightarrow\:\:\:\sf s_{2} = {\sf{\purple{2000m}}}$

$\small{\underline{\bf{Now, \:Distance \:between \:them\: =\: s_{2} - s_{1}}}_{}}$

$\hookrightarrow\:\:\:\sf 2000 - 1500$

$\hookrightarrow\:\:\:\bf \pink{500m}$

${\underline{\bf{Hence, }}}$

Total Distance between them after $\bf{100 \:seconds}$ is $\bf\orange{500m}$
