2,143 Pointshaving trouble with this question ,any ideas ?!
The method below checks the speed of a car and returns a string value: either "safe" or "unsafe". Return "safe" if: The car_speed passed in as an argument is greater than or equal to the number 40. The car_speed passed in as an argument is less than or equal to the number 50. Otherwise, return "unsafe". Hint: You should use the && logical operator to accomplish this task. :)
def check_speed(car_speed)
# write your code here
print "what is your speed?"
car_speed = gets.chomp.to_i
if ( car_speed >= 40 ) && ( car_speed <= 50 )
puts "safe"
end
else
puts "unsafe"
end

11,108 PointsSorry I have no idea what I was thinking, try putting return instead of puts.

11,108 PointsOh just seen that you put an end after the first 'if' should probably look like :
def check_speed(car_speed)
# write your code here
print "what is your speed?"
car_speed = gets.chomp.to_i
if ( car_speed >= 40 ) && ( car_speed <= 50 )
return "safe"
else
return "unsafe"
end

for some reasons doesn't work. Could you help, please
