Divide 496 by 8. That will give you the speed in miles per hour.
Watch closely, and take notes:400/5 = 80 miles per hour.? ? ?

1.4:1 in favor of the train.
speed = distance/time = 100mi/2h = 50mi/h
170 miles per hour
the trains speed is 85 miles an hour the answer is very simply the only thing that you need to do is divide 1020 by 12 and you get 85
1600 / 80 = 20 hours by train 1600 / 200 = 8 hours by plane it will take 20 - 8 = 12 hours more by train
'A' is slower. 'B' is faster. 'A' covers 220 miles, while 'B' covers 310 miles. 'B' gained 90 miles on 'A'. Since 'B' gains 18 miles on 'A' in each hour, it took (90/18) = 5 hours for 'B' to gain 90 miles on 'A', so both stated distances were covered in 5 hours. Speed of 'A' = 220/5 = 44 Speed of 'B' = A+18 = 310/5 = 62
140 miles
Just multiply the 45 hours by the speed.
