If a girl walks for 6 kilometres in 30 minutes when
walking with the same speed consistently, how many kilometres can she walk in 50 minutes?
You can divide or multiply the distance and the amount of time by the same amount, and the
speed does not change.
Since the girl walks 6 kilometres in 30 minutes, she walks 2 kilometres in 10 minutes (divide
each by 3).
Since 10 minutes 5 = 50 minutes, then we can find the distance the
girl walks in 50 minutes by multiplying 2 kilometres by 5.
Since , then the girl walks 10
kilometres in 50 minutes.
