Answer 2

Answer:

• The car will take 12 hours to travel 480 km.

Explanation:

Given that:

• The speed of a car is 40 km/h.

To Find:

• Time taken by the car to travel 480 km.

Formula Used:

$\sf{Time\;taken=\dfrac{Distance\;to\;be\;covered}{Speed\;of\;the\;car}}$

Solution:

As we know that,

$\sf{Time\;taken=\dfrac{Distance\;to\;be\;covered}{Speed\;of\;the\;car}}$

Substituting the values,

$\sf{Time\;taken=\dfrac{480}{40}}$

Cutting off the zeros,

$\sf{\longrightarrow \dfrac{48\!\!\!\not{0}}{4\!\!\!\not{0}}}\\\\\longrightarrow \dfrac{48}{4}$

Dividing 48 by 4,

$\sf{\longrightarrow 12}$

Hence, the car will take 12 hours to travel 480 km at the speed of 40 km/h.

More formulas:

$\sf{Speed=\dfrac{Distance\;to\;be\;covered}{Time\;taken}}\\\\Distance\;to\;be\;covered=Speed\times Time\;taken$
