**SDG** SDG 5 - Gender Equality https://www.footholdamerica.com/faqs/how-long-for-us-maternity-leave/ **Task definition** Read the code on the electric box at the location. Add all the code numbers one by one and imagine, that the resulting number is the data on your cars speed dial in km/h. Calculate "X" by counting how many times your speed is lower than default town speed limit in Estonia. Now resolve one of the following equations and see how many weeks are guaranteed by goverment of USA to women workers for maternity leave (for example, in UK it is 52 weeks): **Solution move** 1. Add all the codes one by one 2. Calculate X **Mathematical calculation step** 1+5+9+2+5+3=25 50/25=2 2\*4-8/2-4=0 cos(90deg)+2\*X-4=0 **Connection to the study** My study field Traffic safety is related to the part where you have to find the number that is the  data on your cars speed dial in km/h.
