Total distance =165 miles Avg speed = Total distance/Total time Let avg speed for ist part be x Let total time for ist part by y X = 165/y (ist part)…………..(1) (x-22) = 165/(y+2) (2nd part)………….(2) Now small magic Xy = 165 from eqn 1 (x-22)(y+2) = 165 from eqn 2 Xy + 2x – 22y – 44 =165 165 + 2x – 22y – 44 = 165 165 cancel 165 2x – 22y – 44 = 0 2(165/y) – 22y – 44 = 0 330/y – 22y – 44 = 0 Multiply through by y -22y2 – 44y + 330 = 0 Using almighty formula Y becomes either -5 or 3 Since time cant be negative Y = 3 hours So x = 165/3 = 55 miles per hour 10 Likes 1 Share |

Hi Op, I disagree with all the workings above. Both the one by Teeneyo and the one placed on ChatGPT. This is because your question is not a complete question. You said he traveled 165miles, at what speed (we don't know). When he was coming back, he reduced the speed by 22miles per hour, and the return journey then took 2 hours. Chatgpt may be 75% wrong on complex maths, especially when it involves issues represented by linear equations. I am saying this from experience! Don't be deceived. Get the complete question and finding your way to the answer would be a glide thru. Peace🤞 |

yemre: Teeneyo and the one by ChatGPT are 100% right. You are the one that does not understand the question. |
