Given :

  • Distance = 175
  • Time 1 = 4 hours


\\ \\

To find:

  • Different between two speeds when distance is same.


\\ \\

Solution:

Part 1 :

In first part we will find speed 1 in which time is 4 hours

we know:-


\bigstar \boxed{ \rm speed = (distance)/(time) }

So:-


\dashrightarrow\sf speed_1 = (distance)/(time_1)


\\ \\


\dashrightarrow\sf speed_1 = (175)/(4)


\\ \\


\dashrightarrow\bf speed_1 = 43.75 \: km {h}^( - 1)

Part 2

In first part we will find speed 2 in which time is 3 hours

Again:


\bigstar \boxed{ \rm speed = (distance)/(time) }


\\ \\


\dashrightarrow\sf speed_2 = (distance)/(time_2)


\\ \\


\dashrightarrow\sf speed_2 = (175)/(3)


\\ \\


\dashrightarrow\bf speed_2 = 58.33kmh^(-1)


\\ \\

Part 3

In this part we will find different between speed 1 and speed 2


\bigstar \boxed{\rm Difference = speed_2 - speed_1}


\\ \\

So :


\dashrightarrow\sf Difference = speed_2 - speed_1 \\


\\ \\


\dashrightarrow\sf Difference =58.33 - 43.75\\


\\ \\


\dashrightarrow\bf Difference =14.58kmh^(-1)\\


\\ \\


\therefore \underline {\textsf{\textbf{Difference in speed between two cars is \red{14.58km/h}}}}
