Runner a is initially 8.2 km west of a flagpole and is running with a constant velocity of 5.8 km/h due east. runner b is initially 3.0 km east of the flagpole and is running with a constant velocity of 5.6 km/h due west. what will be the distance of the two runners from the flagpole when their paths cross?

Step-by-step explanation:

Given

Runner A is 8.2 km from pole and Runner  B is 3 km from pole

Runner A velocity

Runner B velocity

let A traveled x km in t hr

so B travels 8.2+3-x km in t hr

x=5.69 km

therefore Distance of A from pole is 8.2-5.69=2.3 km

Distance of B from pole B is 5.69-3=2.69 km

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
