Lucy and her family are going for a hike. the trail they are hiking starts at 32.8 feet below sea level and ends at 35.98 feet above sea level. what is the total distance they hiked?

Distance=68.78 ft

Step-by-step explanation:

With this data, we can find the total vertical distance Lucy and her family hiked, which will be given by the distance above sea level plus, the one below sea level. Both have to be considered, given that the distance is accumulative.

Distance=32.8 feet+35.98 feet=68.78 feet.

ik how do do this just give me a few minutes and i will give it to

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
