Question

A truck can cover a certain distance in 6 hours at the speed of 48 km per hour if the speed of the truck is reduced to 36 km per hour how much time will take for the truck to travel the same distance​

Answer 1

Answer:

24 hrs.

Explanation:

Given,

A truck covers a distance in 6 hrs at the speed of 48km/hr. If the speed is reduced by 36km/hr

How much time will it take to travel the same distance.

We know that,

$\bullet \: \: \boldsymbol{d = s \times t}$

Where,

• $d$ denotes the distance covered.
• $s$ is the speed = 48km/hr.
• $t$ is the time taken = 6 hrs.

$\implies \: d = 48 \times 6$

$\implies \: d = 288$

∴ Distance coverd by the truck is 288km.

Now,

Speed is reduced by 36km/hr

$\therefore \rm \: New \: speed = 48 - 36$

$\rm = 12km/h$

Time it will take to cover is given by,

$\implies \: \boldsymbol{ t = \dfrac{d}{s} }$

Substitute the values,

$\implies \: { t = \dfrac{288}{12} }$

$\implies \: { t = 24}$

∴ Time it will take is 24 hrs.

Formulae:

$\bullet \: \: s = \dfrac{d}{t}$

Where,

• $d$ denotes the distance covered.
• $s$ is the speed.
• $t$ is the time taken.
