On a day when the speed of sound in air is 94.0 km/hr you yell across a canyon. you hear your voice echo back from the opposite canyon wall 1.03 min after you first yell. what is your distance in meters from the other side of the canyon? Whoever does this thank you so much, you're doing God's work!

Step-by-step explanation:

speed of sound in air = 94 km/hr.

with a time of 1.03 min.

find distance traveled in meters

solution:

distance = velocity x time

              = 94 km  x      1 hr.     x  1.03 min  x   1 000 m

                      hr.          60 min.                              1 km

              =  1,613.7 m

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
