Answer 1

A glacier moves a distance of 2/3 km in 4 months

To get the average speed per month, we will divide the distance by the period

Mathematically,

distance = 2/3 km = 0.667 km, time = 4 months

Speed = distance / time

Speed = (2/3) / 4 = 2/12 kilometers per month

Speed = 1/6 kilometers per month

Hence, option A is the correct answer
