A motorboat travels 238 kilometers in 7 hours going upstream. It travels 350 kilometers going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
Rate of the boat in still water:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

its a, i had the same answer, its from study island right
