An earthquake wave travels through 55 km of rock in 25 seconds . Which equation represents the relationship between t, the numbe
r of seconds, and d, the total distance the wave travels?
1 answer:
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

c)
Step-by-step explanation:
Use 49 instead of 14 for 7²
Reason: 7² = 7 * 7 = 49
Not 14 as 7*2 = 14
Answer: -16
Step-by-step explanation:
-12-4=-16
Making -16+4=-12
