Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 =  ; y = 20 sin 45 ; y= 14.14 miles
 ; y = 20 sin 45 ; y= 14.14 miles
cos 45 =  ; x = 20 cos 45 ; x = 14.14 miles
 ; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
 =
 =  +
 + 
     =  +
 + 
      = 3131.08
 =
 = 
z = 55.96 miles
 
        
             
        
        
        
Seismic waves
Step-by-step explanation:
An earthquake releases energy as shock waves, the so-called seismic waves, which ripple across the earth's surface. The seismic waves created as they move from the epicentre an earthquake vary.

Answer:
<h2>A. 4 in</h2>
Step-by-step explanation:
Collinear points are points that lies on the same straight line. If the points E, F and G are collinear points, then the three points lies on the same straight line. 
If E is between F and G, the FE+EG = FG
EG = FG - FE
Given FE = 3 in and FG = 7 in
On substituting into the expression above to get EG;
EG = 7in - 3in
EG = 4in
Hence the length of EG is 4in
