If Midway Island is 1935 km northwest of Hawaii the Pacific plate moving to Northwest at 9 cm a year how long ago was located over hot spot that formed it?

To calculate how long ago Midway Island was located over the hotspot that formed it, we can use the formula:

```

Time = Distance / Rate

```

where:

* Time is the time in years

* Distance is the distance in kilometers

* Rate is the rate of movement in centimeters per year

In this case, the distance is 1935 km and the rate is 9 cm per year, so the time is:

```

Time = 1935 km / 9 cm/year = 215 years

```

Therefore, Midway Island was located over the hotspot that formed it about 215 years ago.
