Question

Steve and his daughter went on 30- mile backpacking trek in Yosemite national park. They hiked 7.7 mi the first day , 6.4 the second day and 8.0 mi the third day. How much farther did they have to go ?

Answer 1

To answer this question you basically have to add up day 1, day 2 and day three then take it away from 30 so.....

7.7+6.4+8.0=22.1

30-22.1=7.9 so they have 7.9 miles left to walk
