While driving from Chicago, Brent had a visibility problem due to the fog. After 1 1/2
1 answer:
1) Let x be the original speed that he was driving; x mph ---> 1.5 hours x+44 mph --> 2.5 hours 1.5x + 2.5(x+44)=206 1.5x+2.5x+110=206 4x=206-110 4x=96 x=24 Therefore, he was travelling at 24 mph in the fog. 2) Let x be the speed of 1 snail, The other snail travels at the speed of x+1 cm/min 23x+23(x+1)=391 <-- solve for x 23x+23x+23=391 46x=368 x=368/46 x=8 Therefore one of the snail travels at 8 cm/min while the other goes at 9 cm/min 7) Let x be one crew Then the other crew would be working at x+0.5 3.2x+3.2(x0.5)=8 <-- solve for x 3.2x+1.6x=8 4.8x=8 x=8/4.8 x=1.6666 or 1.7 miles Therefore, one of the crew does 1.7 miles per day and the other crew does (0.5*1.7)=0.85 miles Hope I helped :)
