Two hikers are 55 miles apart and walking toward each other. They meet in 10 hours. Find the rate of each hiker iſ one hiker wal
ExtremeBDS [4]

Answer:

Speed of hikers are 4.4 mph and 7.7 mph

Step-by-step explanation:

Two hikers are 55 miles apart and walking towards each other.

They meet after 10 hours.

Let the speeds of hikers are S and S' mph.

One hiker walks 3.3 mph faster than the other,

S = 3.3 + S'

S' = S - 3.3

Distance traveled by the hiker with higher speed S = Speed × Time

d_1=S\times 10

d_1=10S

Distance traveled by the slower hiker d_2 = (S - 3.3) × 10

Total distance between them = 55 miles

d_1+d_2=55

10S + 10(S - 3.3) = 55

20S - 33 = 55

20S = 88

S = 4.4 mph

Speed of first hiker = 4.4 mph

Speed of second hiker = 4.4 + 3.3 = 7.7 mph
