Let n be the man's walking rate. Then:
9/n+9/27=3&1/3
243+9n=90n
243=81n
n=3
The man's walking rate was 3 mph

Answer:
Step-by-step explanation:
M = 2J
M = H + 7
M + J + H = 53
Then combine first two equations and solve in terms of J:
2J = H + 7 --> H = 2J - 7
Substitute for H & M in last equation:
2J + J + 2J - 7 = 53
5J - 7 = 53
5J = 60
J = 12
Then plug J into other equations:
M = 24
J =12
H = 17
