Answer:

X = 7.5

Step-by-step explanation:

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ? ​
jekas [21]
<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

  • Since 1 hour = 60 minutes..
  • 5 hours = 300 minutes ..

• Thus , The two given statements are :-

  • 14km -----------------> 25 minutes..
  • And, x km -------------> 300 minutes..

<h3><u>We know that , </u></h3>

  • The distance travelled by car and the time taken by the car is directly proportional to each other....

<h3>So , </h3>

\frac{14}{25}  =  \frac{x}{300}

= x = 168km

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)
