Question

If they went 5 km in 1 1/2 hours what was their rate?

Answer 1

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.

Answer 2

If they went five km in 1&1/2 hours then their rate would be:
$\frac{5}{1&1/2}$= 5÷$\frac{3}{2}$= 5×$\frac{2}{3}$= $\frac{10}{3}$=3$\frac{1}{3}$

so 3$\frac{1}{3}$ km per hour
