Question

Two trains start at he same point at the same time and simultaneously travel in opsonist direction. The speed of the first trains is 60 mph and the speed of the second train is 70 mph. How far apart will they be 3.5 hours?

Answer 1

Answer: 455 mph

Step-by-step explanation:

if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210

then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time

70 x 3.5 = 245

finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference

210 + 245 = 455
