Problem:If the continents are drifting apart at a constant speed of 3 cm/year, and Africa and South America are separated by 6.4 × 10^6 cm, how long has this drift been occurring?Solution:To determine the duration of the drift, we will use the formulaTIME = DISTANCE/SPEEDGiven:The separation distance between Africa and South America is 6.4 × 10^6 cmThe rate of drift is 3 cm/yearSubstituting the known values into the formula:TIME = 6.4 x 10^6 cm / 3 cm/yearTIME = 2.13 x 10^6 yearsConclusion:The drift of the continents has been occurring for approximately 2.13 million years.Hope it helps!#keeplearning#dontstoplearning
