The answer is 4 m/s.
In the first 5 seconds, a body travelled 10 meters. In the first 10 seconds of the travel, the body travelled a total of 30 meters, which means that in the last 5 seconds, it travelled 20 meters (30m + 10m).
The relation of speed (v), distance (d), and time (t) can be expressed as:
v = d/t
We need to calculate the speed of the second 5 seconds of the travel:
d = 20 m (total 30 meters - first 10 meters)
t = 5 s (time from t = 5 seconds to t = 10 seconds)
Thus:
v = 20m / 5s = 4 m/s
I am pretty sure it's 44 degrees.
The GCF is 36 since 36 can go into 144 (:

Answer:
14
Step-by-step explanation:
<u>Find a number that is 4 more that is 4 more than 6 plus 4</u>
4 more than 6 plus 4
6 + 4 = 10
4 more means 4 + (6 +4)
= 14
David should buy Car A because it covers more miles in one gallon than Car B
Step-by-step explanation:
Given
Distance traveled by Car A = 
Gallons used by Car A = 
Distance traveled by Car B = 
Gallons used by Car B = 
In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons
So,
Distance traveled by Car A in one gallon = 
Distance traveled by Car B in one gallon = 
We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon
So,
David should buy Car A because it covers more miles in one gallon than Car B
