Tenzin walks in the mountains. Tenzin has a rule to estimate the time it will take her to complete a walk in the mountains. She uses an average speed of 5 km / h for the distance she will walk and then adds on 1 minute for every increase of 10 metres in height. Tenzin plans to walk 12 km in the mountains with an increase of 800 metres in height. Use Tenzin's rule to work out an estimate for the time it will take her to complete this walk.
