Courses Plus Student 5,638 PointsI have not been able to complete this challenge. What is the correct answer?
My response would be:
if (car_speed >= 40) && (car_speed <= 50)
return safe
else
return unsafe
def check_speed(car_speed)
if (car_speed# write your code here
end

You need to test car_speed
against two things (being greater or equal to 40 or less than/equal to 50) - that makes it "safe". The other option is "unsafe" but that's the simple bit!
So, to test car_speed
against 40 would look like car_speed
>= 40. To test against 50 looks like car_speed
<= 50. Using an if
statement, as you have done and the && operator to check two conditions (as you have done), you then need to return a string (surround with inverted commas) and conclude the if
statement with the keyword end
.
So, you've missed the string piece and the end
keyword. the rest of what you've done is fine! The code looks like:
def check_speed(car_speed)
# write your code here
if car_speed <= 50 && car_speed >= 40
return "safe"
else
return "unsafe"
end
end
I hope that helps.
Steve.
P.S. You can omit the return
keyword - it isn't necessary but it does help with readability of the code.
