Since the question is asking for the time units to be in hours, you want to convert 30 minutes to an hour; 0.5
We’re able to use the basic motion formula for velocity to work out this question.
Velocity = distance / time
Velocity = 5 / 0.5
Velocity = 10km/h
Therefore, Stanley’s average speed was 10 kilometres per hour. :)
Answer: y=4x+7 is the equation
If x is the amount of time Gillian takes,
1/10 - 1/x = 1/25
Therefore, the answer is A
