Ifeel sad because i'm in advanced and i can't figure this problem out:
a high speed train travels 100 miles in 2/3 hour. which speed represents the rate of the train ?
f: 50 mph
g: 75 mph
h: 100 mph
i: 150 mph

It would 150 mph because the train traveled more that 100 miles in less then an hour meaning the train had to travel faster than 100 mph. if you notice the speed is in miles per hour so if you are going 100 mph that means you traveled 100 miles in one hour.
