Answer 2

Answer:

• The person will take 2.5 hours to cover the same distance at a speed of 40 km/h.

Step-by-step explanation:

Given that:

• A person driving at 50 km/h reaches his destination in 2 hours.

To Find:

• If the speed of the person had been 40 km/h, in what time would he covered the same distance.

Finding distance covered by the person:

As we know that:

• Distance = Speed × Time

Here,

• Speed = 50 km/h
• Time = 2 hours

Substituting the values,

$\sf{Distance = (50\times2)\;km}$

Multiplying the numbers,

$\sf{= 100\;km}$

Hence,

• The distance traveled by the person is 100 km.

Finding time if speed would be 40 km/h:

As we know that:

• Time = Distance/Speed

Here,

• Distance = 100 km
• Speed = 40 km/h

Substituting the values,

$\sf{Time=\left(\dfrac{100}{40}\right)\;hours}$

Dividing the numbers,

$\sf{=2.5\;hours}$

Hence,

• The person will take take 2.5 hours.
