a local Transit Agency wants to estimate the average time it's bus drivers take to complete their downtown route during rush hour in order to estimate the average Roots time during rush hour the agency plans to take a random sample of 76 route times from routes driven during rush hour in the past 5 years

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
