Question

A car travels 182 kilometers in 4 hours with the constant speed. how much time will it take traveling 42 kilometers

Answer 1

55.38 min

Explanation:

A car travels,

182 km ⇒ 4 hours

And we have to find the time that it takes to travel 42 km .

Lets make a equation.

Let the unknown time be x

182 km ⇒ 4 hours

42 km ⇒ x

To make easy let's km in to meters and hours in to minutes

182000 m ⇒ 240 min

42000m ⇒ x

Now use cross multiplication.

`182000x=240*42000\\`

`182000x=10080000`

`(182000x)/(182000) =(1008000)/(182000)`

`x =55.38min`

Hope this helps you.
