Hey Chris,

You have to break down the rate into it's component pieces: Jet and Jetstream

2,600 = (Jet Rate - Jetstream Rate) * 4

6,650 = (Jet Rate + Jetstream Rate) *7

650 = Jet Rate - Jetstream Rate

950 = Jet Rate + Jetstream Rate

By adding equations we get:

1,600 = 2 *(Jet Rate)

**Jet Rate = 800 mph**

Then by plugging back in we get:

650 = 800 - Jetstream Rate

**Jetstream Rate = 150 mph**
