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
18
The LCM is 18.
9x2=18
2x9=18
Q=33/10-r/10 R=33−10q
