Sage hiked from the start of the trail to look out point. she then hiked back to giant boulder to camp for the night. what was the total distance, in miles, that sage hiked? pinecone trail nature center 1 1/2 miles giant boulder 4 1/4 mileslookout point 8 3/4 milesa) 21 3/4b) 13 1/4c) 4 1/2d) 4 1/4

Option b -

Step-by-step explanation:

Given : Sage hiked from the start of the trail to look out point. she then hiked back to giant boulder to camp for the night.

To find : What was the total distance, in miles, that sage hiked?

Solution :

The distance of Pinecone Trail

Nature center =

Giant Boulder=

Look out point =

Now, According to question

Sage hiked from the start of the trail to look out point.

Distance covered is  

She then hiked back to giant boulder to camp for the night.

The distance she traveled extra is

The total distance traveled by Sage is

Therefore, Option b is correct.

The distance traveled by Sage is

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

answer: f = 32.2m

step-by-step explanation: that is the answer
