Answer:
2.2 m/s
Step-by-step explanation:
Step one
Given data
An earthquake wave travels through 55 km
hence distance = 55 km
time taken = 25 seconds
<u>Required</u>
<u>the expression relating t and d</u>
Step two:
we know that velocity is
Speed= distance/time
speed= 55/25
Speed= 2.2 m/s
No because a square pyramid must hav a square for its base and a square is not a triangle
answer is not possible
M < 2 will be 180 - 122 = 58 degrees
< 3 is opposite < 1 so it will be = 122 degrees
The answer is 2,596 so it would be C
