Help its for science but its also math !!!

Question

Scientists calculate that parts of the himalayas are growing at a rate of 6.1 mm per year. At this rate, in how many years will the himalayas have grown 1 m taller?

Answer 1

To solve this problem, we first convert 6.1 mm to 0.0061 m because 1 mm = 0.001 m (the prefix "milli" means "one-thousandth").  Now, we can divide 1 m / 0.0061 m to get 163.9 years.  We can say that it will take about 163.9 years for the Himalayas to grow another meter.
