WebWhat is the average speed of the biker? Answer Let the time while riding the bike upwards be t1. Let the time while riding downwards be t2. Let the distance be d. Avg. Speed = d/t = 2d/t1 + t2 Upwards: Since 1 = d/t1, Therefore t1 value = d/1 = d Downwards: Since 9 = d/t2, Therefore t2 value = d/9 WebThe expression for the average velocity between two points using this notation is – v = x(t2)−x(t1) t2−t1 v – = x ( t 2) − x ( t 1) t 2 − t 1. To find the instantaneous velocity at any position, we let t1 = t t 1 = t and t2 = t+Δt t 2 = t + Δ t. After inserting these expressions into the equation for the average velocity and ...
