There are a fews ways to solve this. I am going to use the distance equation d = rt.
d = distance = 600 r = speed = ????? t = time = hours = 2.5
Lets find the rate/speed by plugging in what we know. d = rt 600 = r2.5 600 /2.5 = r2.5 / 2.5 240 = r r = 240
Now we got the rate/speed we can solve our problem. It wants to kow how long it will take to travel 1500 more miles from the 600 miles that has already traveled
d = rt d = 1500 r = 240 t = ?????
1500 = 240t 1500 / 240 = 240t / 240 6.25 = t t = 6.25. It will take 6.25 or as fraction 6(1/4) hours more.
