Ruby Ruby Basics Conditionals A Better "check_speed" Method

This version of the check_speed only prints "speed OK" if the speed is exactly 55 miles per hour.

This version of the check_speed only prints "speed OK" if the speed is exactly 55 miles per hour. It would be better to allow a range of speeds. Update check_speed with this logic: If we pass a speed of less than 45, check_speed should print "too slow". If we pass a speed of 45 to 60, check_speed should print "speed OK". If we pass a speed of greater than 60, check_speed should print "too fast".

Does anyone knows how to do this?

program.rb 
def check_speed(speed)
  if speed <= 45
    puts "too slow"
  end

  if speed == 55
    puts "speed OK"
  end
  if speed > 60
    puts"too fast"
  end

end

You almost got it but it's in the wording that you have to look. Speed is below 45 so try and do this. speed > 45

After, If we pass a speed of 45 to 60. Mean between 45 and 60 so... speed <= 45 && speed <=60

an you know for the last one.

I don't remember if this test is after the else, elsif and if.

If it is there is a better solution which is

def check_speed(speed) if speed < 45 puts "too slow"

elsif speed >= 45 puts "speed OK"

else speed > 60 puts"too fast" end

end

def check_speed(speed)
  if speed < 45
    puts "too slow"
  end
  if speed > 60
    puts "too fast"
  end
  if speed > 44 && speed < 61
    puts "speed OK"
  end
end

Dimitri Fajardo, the code you wrote didn't work too, it's almost there, it says: "We called check_speed with an argument greater than 60, but it didn't print "too fast"."

Thank you very much for the tips, i will continue trying to understand the logic of this exercices and different ways to do it!

I made a mistake I forgot an end there are 2 of them. I just did it it works

def check_speed(speed)
  if speed < 45
    puts "too slow"

  elsif speed > 60
    puts "too fast"

else speed >= 45
    puts "speed OK"
  end
end
