Question

a car travels 120km in 2hr. its speed in m/s is?​

Answer 1

Solution

Given :-

• Distance cover by car(D) = 120 km
• Taken Time by car (T) = 2 hours

Find :-

• Speed of car

Explanation

Using Formula

★Speed = Distance/Time

So,

➡Speed = 120/2

➡Speed = 60 km/h

We know,

• 1000 m = 1 km

Then,

• 60 km = 60,000m

And,

• 1 hour = 60 min = 3600 second

So, Now change km/h into m/s

➡ 60km/h = 60,000/3600

➡60km/h = 600/36

➡60km/h = 100/6

➡70km/h = 50/3 m/s.

Hence

• Speed of car = 50/3 m/s.
