Svetach [21]

Answer:

distance in east is 1273.78 m

Explanation:

given data

average velocity = 1.32 m/s west =

hike = 5.21 km = 5.21 × 10³ m

average velocity = 3.49 m/s west

average velocity = 0.687 m/s east

to find out

distance in east

solution

we consider here distance in east  is = x

so distance from starting point = 5.21 × 10³ - x        ...................1

and we can say time required to reach end

time required = distance / speed

time required = \frac{5.21 *10^3 - x}{1.32}    ................2

and

time required for 6.44 km west

time required = \frac{5.21 *10^3 - x}{3.49}    ................3

and time required for distance x

time required = \frac{x}{0.687}    ................4

so from equation 2 , 3 and 4

\frac{5.21 *10^3 - x}{1.32} = \frac{5.21 *10^3 - x}{3.49}  + \frac{x}{0.687}

x = 1273.78 m

so distance in east is 1273.78 m

How can this sandstone become an igneous rock?
ICE Princess25 [194]

Answer:Extreme pressure from burial, increasing temperature at depth, and a lot of time, can alter any rock type to form a metamorphic rock. If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock.
