A glacier moves with a speed of 35 nm/s. How many years would it take for the glacier to move 0.9 km? Assume there are 365 days in a year. Answer in units of y.

Respuesta :

d = 0.9 km = 900 m, distance moved
v = 35 nm/s , the speed

v = 35 x 10⁻⁹ m/s
   = (35 x 10⁻⁹ m/s)*(365 days/y)*(24*60*60 s/day)
   = 1.1038 m/y

The time iaken is
t = d/v
  = (900 m)/(1.1038 m/y)
  = 815.365 y

Answer: 815.4 y (nearest tenth)
