A jet travels 1908 miles against a jetstream in 3 hours and 2178 miles with the jetstream in the same amount of time. What is the rate of the Jet in still air and what is the rate of the Jetstream?

636 miles/hr is the rate of the Jet in still air

726 miles/hr  is the rate of the Jetstream

Explanation:

             Rate or speed = distance / time taken

rate = 1908 miles / 3 hours

       = 636 miles/hr

rate = 2178 miles / 3 hours

       = 726 miles/hr

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
