Answer 2

Required Answer :

$\underline{ \boxed{\sf{ \pmb{The \: \: distance \: \: travelled \: \: by \: \: the \: \: car \: \: in \: \: 5 \: \: hours \: = \: 400 \: km \: \: or \: \: 400000 \: m}}}} \bigstar$

Given :

• Speed of a car = 80 km/h
• Time = 5 hours

To find :

• The distance travelled by the car in 5 hours

Concept :

Here, in this question we are given the speed of a car and the time and we need to calculate the distance travelled by the car in 5 hours. So, for that we will directly apply the given values in the formula of distance.

Distance is the path travelled by an object. It is the product of speed and time.

Formula to calculate distance travelled by a body :

• D = S × t

where,

• D denotes the distance travelled
• S denotes the speed of the object
• t denotes the time taken

Solution :

Calculating the distance travelled by the car :

⇒ Distance travelled by the car = 80 × 5

⇒ Distance travelled by the car = 400

Therefore, the distance travelled by the car in 5 hours = 400 km

We are asked to calculate the distance travelled by the car in both km as well as in m. So, to convert the distance travelled by the car in m, multiply the value by 1000.

As we know,

• 1 km = 1000 m

⇒ Distance travelled by the car = 400 × 1000

⇒ Distance travelled by the car = 400000

Therefore, the distance travelled by the car in 5 hours = 400000 m

Some related formulae :

• Speed = Distance ÷ Time

• Time = Distance ÷ Speed

• Average speed = Total distance travelled ÷ Total time taken
