Find the time (in seconds ) taken for the following journey:
100 km at a speed of 40 km/hour.

9,000 seconds

Step-by-step explanation:

The journey is 100 km long, and you are traveling 40 km/hour. To find how many hours it would take to travel 100 km at that speed, use cross-multiplication, where x represents the amount of hours it would take to travel 100 km:

100/x = 40/1

100 = 40x

Divide both sides by 40 to find the value of x:

2.5 = x

It would take 2.5 hours to travel 100 km at a speed of 40 km/hour.

There are 60 minutes in an hour. Multiple the amount of hours by 60 to find the number of minutes the journey would take:

2.5 * 60 = 150

There are 60 seconds in a minute. Multiply the amount of minutes by 60 to find how many seconds it would take:

150 * 60 = 9000

It would take you 9,000 seconds to travel 100 km at a speed of 40 km/hour.

Hope this helps :)
