# 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
```

yoo thank you so much DImitri Fajardo \o/ you helped me a lot Will continue studying your example to understant this thing, else, elsif ect..I need to master this things) Good lucky with everything man, thank you again

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
```
