The total age of the three children are = 37years
<h3>Calculation of the total age of children</h3>The product of the ages of three children is = 1872.
Let take child 1 = x
child 2 = x
child. 3 = x
Therefore, the age of three children = x³= 1872
Therefore;
X = 12.32448
The age of the middle child = 12.32448 + 12.32448
= 24.64896/2
= 12.32448
Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.

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
Distance traveled by the slower hiker = (S - 3.3) × 10
Total distance between them = 55 miles
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
