Question

A bus has a speed of 36 km/h . How long will it take to cover a distance of 500 m ?

Answer 1

Given

Speed = 36km/ hr

Distance = 500m

Both should have same unit so convert speed or distance.

Speed = 36km/hr

As we know,

1km = 1000m

And

$1 hr = 3600s (60 \times 60)s$

So, divide the given value by (60 \times 60)s and multiply it with 1000

$\dfrac{36 \times 1000}{60 \times 60}$

$Speed= 10m$

To Find:-

Time = ?

Solution

Formula to find time if distance and speed is given.

➣ $Time=\dfrac{Distance}{Time}$

Put the given values..

$Time= \dfrac{500}{10}$

Time = 50s

Additional Information

▪Distance is the path travelled by an object.

▪Speed is the distance travelled by an object in unit time.

Formula to find Speed.

$Speed= \dfrac{Distance}{Time}$

Formula to find Distance.

$Distance=Speed \times Time$

Answer 2

❱•❰

Given:-

• Speed of the bus (v) = 36 km/h [Consider uniform] = 10 m/s
• Distance to travel = 500 m

To Find: Time taken in the journey.

We know,

t = s/v

where,

• t = Time taken,
• s = Distance travelled,
• v = Speed.

∴ t = (500 m)/(10 m/s)

→ t = (50)/(1/s)

→ t = 50 seconds

∴ Time it'll take is 50 seconds.
