Answer 2

$\sf\large\underline{Given:}$

• $\sf{The\: speed\:Soni=2m/s}$
• $\sf{The\: speed\:Tanya=3m/s}$

$\sf\large\underline{To\: Find:}$

• $\sf{How\:far\: apart\:are\:they\: after\:an\:hour}$

$\sf\large\underline{Solution:}$

[At 1st convert the time in second here]

[As we know that, 1hour=3600second]

• [Distance covered by Soni:-]

$\rm{\implies Distance=2*3600}$

$\rm{\implies Distance=7200m}$

• [Distance covered by Tanya:-]

$\rm{\implies Distance=3*3600}$

$\rm{\implies Distance=10800m}$

• [Now, calculate total distance between them]

$\rm{\implies Total\: distance=7200+10800}$

$\rm{\implies Total\:distance=18000m}$

• [Covert distance in km here]
• [we know that, 1km=1000m:-]

$\rm{\implies Total\:distance=18000\div 1000}$

$\rm{\implies Total\:distance=18km}$

Hence,

• Total distance between Soni and Tanya are 18km If they both rides bicycle in opposite direction from the same points
