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

Answer:
7672.50
Step-by-step explanation:
7500×0.23%=17.25
17.25×10=172.50
7500+172.50=7672.50
7/63 can be simplified down to 1/9 because if you were to multiply 7 by 9 you would get 63? or an easier way to do it would be to divide 63 by 7
