Question

By travelling at a speed of 48 Km /hr a car finish a certain journey in 10 hours .To cover same distance in 8 hours the speed of car should be ​

Answer 1

Answer:

• To cover same distance in 8 hours the speed of car should be 60 km/hr.

Step-by-step explanation:

Given that:

• By travelling at a speed of 48 km/hr a car finish a certain journey in 10 hours.

Let us assume:

• To cover same distance in 8 hours the speed of car should be x km/hr.

To Find:

• New speed of a car.

Formula used:

• Distance = Speed × Time

Finding the new speed of a car:

• According to the question.

⟶ 48 × 10 = x × 8

⟶ 480 = 8x

⟶ x = 480/8

⟶ x = 60

∴ New speed of a car = 60 km/hr

Answer 2

Answer:

$\Large \underline {\red{ \sf \pmb{Given}}}$

• ➠ By travelling at a speed of 48 Km/hr a car finish a certain journey in 10 hours .

$\Large \underline {\red{ \sf \pmb{To \: Find }}}$

• ➠ To cover same distance in 8 hours the speed of car should be?

$\Large{\underline { \red{\sf \pmb{Using \: Formula }}}}$

${\underline {\boxed{ \bf{Distance = Speed ×Time}}}}$

${\underline {\boxed {\bf{Speed = \dfrac{Distance}{Time}} }}}$

$\Large{ \underline{ \red {\sf \pmb{Solution}}}}$

Finding the distance covered by car in 10 hours at speed of 48 km/hr

$\implies{\sf{Distance = Speed ×Time}}$

• Substituting the values

$\implies{\sf{Distance = 48×10}}$

$\implies{\sf{Distance = 480 \: km}}$

${\large \star \: {\underline{\boxed{\purple{\rm {\pmb{Distance = 480 \: km}}}}}} \: \star}$

$\begin{gathered}\end{gathered}$

Now Finding speed of car to covered same distance by in 8 hours .

$\implies{\sf{Speed = \bigg( \dfrac{Distance}{Time} \bigg)} }$

• Substituting the values

$\implies{\sf{Speed = \dfrac{480}{8}} }$

$\implies{\sf{Speed = \cancel \dfrac{480}{8}} }$

$\implies{\sf{Speed = 60 \: km/hr}}$

${\large \star \: {\underline {\boxed {\purple{\rm \pmb{Speed = 60 \: km/hr}}}}}} \: \star$

$\Large\underline{ \red{ \sf\pmb{Therefore}}}$

• ➺ To cover same distance in 8 hours the speed of car should be 60km/hr

$\Large\underline{ \red{ \sf\pmb{Know \: More }}}$

$\implies\begin{gathered}\begin{gathered} {\boxed{ \sf{Time = \bigg(\frac{Distance}{speed }} \bigg)}}\end{gathered}\end{gathered}$
