Distance and Time Calculation
Mwambui walks 100 metres in 3 minutes. If she continues walking at the same speed, how far will she have walked after 30 minutes?
Method 1: Using Ratio
If 3 minutes = 100m, then 30 minutes = ?
30 Γ· 3 = 10 (times)
Distance = 100m Γ 10 = 1,000m
Method 2: Using Rate
Speed = 100m Γ· 3 min = 33.33... m/min
Distance = Speed Γ Time
Distance = 33.33... Γ 30 = 1,000m
