Question

Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of 3.5 cm/year. (a) What distance does it move in 1 s at this speed?

Answer 1

Answer:

Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm

Explanation:

Given ;

Average speed = 3.5cm/year

Time= 1 s

Distance = speed × time

Number of seconds in a year = 31536000 sec/year

Distance = 3.5 cm/year × 1/31536000sec/year × 1 s

Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
