Answer:
22.35 m/s
Step-by-step explanation:
The distance is always a positive unit, so distance traveled (d) = 15 miles 
Time (t) = 0.3 hours
Time (t) = 0.3 * 60 = 18 minutes
 (1 hour = 60 minutes)
Velocity (v) = ?
The formula of distance is: d = v*t
=> v = d/t = 15/18 = 0.83 miles/minute 
we can also calculate velocity is meter/sec, for that
1 minute = 60 sec
=> 18 mins = 18*60 = 1080 sec
1 mile = 1609.34 meters
=> 15 miles = 15 * 1609.34 = 24,140 m
hence,
v = 24,140/1080 = 22.35 m/s

Answer:
Answer: √49
___________
√49 = 7
Step-by-step explanation:
The area of a square is equal to the square of its side or the product of its side and its side.
A = s², because the sides of a square are congruent.
