Answer:
The total number of hikers are 427
Step-by-step explanation:
Let:
The number of bikers = x
The number of hikers = y
There are 178 more bikers than hikers
y = x + 178
if there are 676 people in the park total how many people are hikers?
Hence:
x + y = 676
we substitute x + 178 for y
x + x + 178 = 676
2x + 178 = 676
2x = 676 - 178
2x = 498
x = 498/2
x = 249
y =x + 178
y = 249 + 178
y = 427
Therefore:
The number of bikers = x = 249
The number of hikers = y = 427
The total number of hikers are 427
