Question 551353


Tom traveled a distance of 265miles. He drove at 40mi/hr during the first part of the trip and at 35mi/hr during the remaining part. If he made the trip in 7hours, how long did he travel at 40mi/hr? Please thank you <3 And sorry for the trouble :( Happy New Year, tutors! <3


Let time he drove at 40 mph be T
Then time he drove at 35 mph = 7 – T


Distance at 40 mph + distance at 35 mph = total distance


Therefore, 40(T) + 35(7 – T) = 265
40T + 245 – 35T = 265
5T = 20


T, or time he drove at 40 mph = {{{20/5}}}, or {{{highlight_green(4)}}} hours
