A river flows with a speed of vr. The boat travels distance of 25 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative vr Write an algebraic expression; do not use numerical values except for the angles.…Suppose an object moves along a line at 10 m/s for 0sts2 s and at 16 m/s for 2While entering a freeway, a car accelerates from rest at a rate of 2.81 m/s² for 13.3s.
