Question 471850
We can find the velocity of each in kilometers per minute:


*[tex \LARGE V_{Leah} = \frac{10 km}{55 min} \approx .18\frac{km}{min}]


*[tex \LARGE V_{Liza} = \frac{10 km}{50 min} = .20\frac{km}{min}]


Then use unit multipliers to convert km/min into each unit. For example, from km/min, you could multiply by 1000m/km, then by 1 min/60 s to obtain the velocity in m/s.
