We have 6, four-hundred pound men, in the back seat of a 1976 Gremlin traveling at 105 miles per hour, if 2 of the 400 men jump out at the 10 mile mark, and the car gains 25 more miles per hour, how long will it take the car to travel 50 miles???

assuming no one else jumps out of the car (at over 100mph!!!) then you work it out in two parts like this:
time = distance/velocity
i) t1 = 10miles/105mph = 0.095hours
ii) t2 = 40miles/130mph = 0.307hours
add t1 and t2 for total time = 0.095 + 0.307 = 0.4hours = 24 minutes. (60mins/10 and then *4)

At 105 mph:
time = distance / speed = 10 / 105 = 0.0952 hours = 5.7 minutes
Speeding up to 130 (assuming instantaneous acceleration):
time = distance / speed = 40 / 130 = 0.3077 hours = 18.46 minutes.
Add the two times together ... 24.16 minutes to travel 50 miles.

who knows but how the heck did you get 6, 4 hundred pound men in the back seat? That's amazing!

I did'nt think a Gremlin could go 105mph.
