Answer:
No I dont agree with Mai. As both the slug and snail are moving with constant speed.
Step-by-step explanation:
Given that:
A slug travels 3 centimeters in 3 seconds.
Speed of slug = distance/ time = 3/3 = 1 cms^-1
A slug travels 3 centimeters in 3 seconds.
Speed of snail = distance/ time = 6/6 = 1 cms^-1
Hence both have constant speeds only the time span for snail is increased which gives more distance it doesn't means that it had covered more distance.
i hope it will help you!
