Question 11
Three friends, Alex, Ben and Charlie, are participating in a 1600-meter inline skating race. The race results are as follows:
- Alex finishes the race first.
- Ben finishes 18 seconds after Alex.
- When Ben finishes, Charlie still has 120 meters left to skate.
- Charlie takes 15 more seconds to reach the finish line after Ben.
Assuming all three skate at constant speeds, how long, in seconds, did Alex take to finish the race?
- Alex finishes the race first.
- Ben finishes 18 seconds after Alex.
- When Ben finishes, Charlie still has 120 meters left to skate.
- Charlie takes 15 more seconds to reach the finish line after Ben.
