Acar travels 240 km in 2.0 hrs and a sprinter travels a 100. m in 9.5 s. which is traveling faster and by how much?

Car: (convert first the units)
240 km * (1000 m /1 km) = 240000 m
2 hr * (3600 s / 1 hr) = 7200 s
v = d/t
v = 240000/7200
v = 33.33 m/s

Sprinter:
v = d/t
v = 100/9.5
v = 10.53 m/s

thus the car travels faster than sprinter by 33.33 - 10.53 = 22.8 m/s

Ireally don’t know bruh

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
