Answer:
16 mph
Step-by-step explanation:
Givens:
4 hours total time
48 miles total distance
So our equation should look like this.
48 = 2x(2) + x(2)
Where x = speed second half of trip.
x = 8
x*2 = 16 mph
That is to difficult for my my g
Well to do scientific notation u have to use 10 then an exponent
example:
2.9867 x 10^10= 29,867,000,000
so u need exponents to do scientific notation.
18 - 2 = 16
8n = 16
Divide
N = 2
