Question

5. A car is travelling at a speed of 72 km/hr. How far will it travel in 25 minutes?​

Answer 1

Answer:

car travel in one hr = 72km

So, the car travel in one minute = 72km/60min=6/5

therefore car travel in 25 minutes = 6/5*25

= 30km

Answer 2

Given :

• Speed of a car = 72 km/hr
• Time in which the car travels the distance = 25 minutes

To find :

• Distance travelled by the car

Knowledge required :-

• 1 min = 1/60 hours
• Formula to calculate distance :-

⠀⠀⠀ Distance = speed × time

Solution :

Time in which the car travels the distance = 25 minutes.

• Firstly, we will convert the time from minutes into hours.

As we know,

• 1 min = 1/60 hr

Divide the value by 60 to convert it from minutes into seconds.

⠀⠀⠀⇒ Time = 25 min = 25/60 hr

⠀⠀⠀⇒ Time = 5/12 hr or 0.42 hr

⠀⠀⠀⇒ Distance = Speed × time

⠀⠀⠀⇒ Distance = 72 × 5/12

⠀⠀⠀⇒ Distance = 6 × 5

⠀⠀⠀⇒ Distance = 30

∴ Distance travelled by the car in 0.42 hours and at the speed of 72 km/hr is 30 km.

⠀⠀⠀⠀⠀⠀Know MorE ::

• Distance is the path travelled by a body in a particular time.
• Speed is the distance travelled by an object in a particular time.

⠀⠀⠀Some related formulae :-

• Speed = Distance/Time
• Time = Distance/Speed
