First of all you find out how much they go in 18 minutes:
1 minute = (4/7)/18
Times this by 30, to get how far he gets in 30 minutes.
((4/7) / 18)*30 = <span>0.952 (3 DP)
In 30 minutes the person walks 0.952 (3DP) of a mile

Answer:
x = -1/7 Or 0.143 (3 dec)
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3
= 24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
21x/21 = -3/21
x = -1/7
Or 0.143 (3 dec)
