Answer:
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 :)
