Battery packs in electric go-carts need to last a fairly long time. The run-times (time until recharging is needed) of the battery packs made by a particular company are Normally distributed with a mean of 2 hours and a standard deviation of 20 minutes. Battery packs that have a runtime in the highest 10% of the run-time distribution are highly sought after by go-cart drivers. How long does the battery pack have to last for it to fall in this highly sought-after class? (Enter the number of hours as a whole number and the number of minutes as a decimal rounded to 1 decimal place.) and hours minutes
