Answer:
48 km/h
Step-by-step explanation:
Distance = 120 km
Time = 2½ h
Speed = ?
We know that
Speed = Distance/Speed
Let,
Speed = v km/h
=> v = 120/(2½)
=> v = 120/(5/2)
=> v = 120 × 2/5
=> v = 24 × 2
=> v = 48 km/h
Average speed is 48 km/h
14+6a-8=18
The solution to the given equation 14 + 6a - 8 = 18 is a = 2.
A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The equation is given in the question, as follows:
14 + 6a - 8 = 18
We have to determine the solution to the given equation.
As per the question, we have
14 + 6a - 8 = 18
Rearrange the terms in the above equation, and solve for a:
6a = 18 - 14 + 8
Apply the arithmetic operations,
6a = 12
Divided by 6 into the above equation, and we get
a = 2
Thus, the solution to the given equation is a = 2.
