Step-by-step explanation:let the distance covered by car of speed 60km/hr bex and distance covered by car of speed 75 km\hr beyfrom 1st condition:x+y=555km₋₋₋₋(1) from 2nd condition x/60+y\75=8 therefore 75x+60y/60Х75=8 therefore 75x₊60y=36000 divide by 15 we get 5x+4y=24000₋₋₋₋(2) multiply eq.(1) by 4 4x+4y=2220(3) subtract eq.(3)from eq.(2) 5x+4y=24000 (-)4x+4y=2220 x=180 substituting x=180 in eq.(1) x+y=555km₋₋₋₋(1) 180+y=555 y=375 therefore the car has covered 375 km.
thus he covered 375 km by bus and 180 km by car
