Answer:
19mph
Step-by-step explanation:
Divide 57 by 3 and you'll get 19mph - the average speed.
Considering the first equation 15 × 0 = -36 + a
15 × 0 = 0
therefore, -36 + a =0
In the second equation
24 × 8 × 0 = 36 - b
Consider the LS
24 × 8 × 0 = 0
Therefore, 36 - b = 0
we are left with the two equations,
36 - b = 0
-36 + a = 0
then, we calculate the number that can be substituted to satisfy the two equations.
solving the equations
b = 36, and a = 36
Therefore, 36 is the number that can be used to substitute a and b in the equations
