Answer:
x = 3
AB = 16
Step-by-step explanation:
Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, the AM = MB
AB = 2AM
5x+1 = 2(8)
5x + 1 = 16
x = 16 - 1
5x = 15
x = 15/5
x = 3
Hence the value of x is 3
Since AB = 5x+1
AB = 5(3) + 1
AB = 15 + 1
AB = 16
We can say that x is the amount of time of the first (easier) part of the hike. Ans t is the amount of time of the second ( more difficult ) part of the hike.
x = 2 - t
And:
3 x + 1.5 t = 5
Answer:
The equation is:
3 * ( 2 - t ) + 1.5 t = 5
We can also solve this equation:
6 - 3 t + 1.5 t = 5
1.5 t = 1
t = 0.66 h = 2/3 h = 40 min.
