Ratio=number of Km / number of hours
Data:
Number of Km=5 Km
Number of hours=1 1/2 hour=1.5 hour.
Ratio=5 km/1.5 hour=3.333... km/h≈3.33 km/h.
Answer; their ratio was 3.33 Km/h.
Check the picture below.
notice the midpoint of the diameter segment, is just 1,9.
also, recall the radius is half the diameter, notice how long the radius is, just 4 units.
12⁷/₁₂ - 5¹⁴/₅
12⁷/₁₂ - 7⁴/₅
12³⁵/₆₀ - 7⁴⁸/₆₀
11⁹⁵/₆₀ - 7⁴⁸/₆₀
4⁴⁷/₆₀
