two trains leave the dallas port going in opposite directions. if one train goes 56 miles per hour, and the other goes 52 miles per hour how long will it take them to be 363 miles apart?
how do i set up this problem?
Use the standard formula
D = RT , (distance = rate x time)
let the time taken by each train be t hours
1st train went 56t miles
2nd train went 52t miles
56t + 52t = 363
108t = 363
t = 363/108 = 3.36111. hrs
= 3 hours and .36111(60) minute
= 3 hrs and appr 22 minutes
give the domain and range of the relation x,2,8,0,-3,and y,5,17,0,5,
To set up this problem, you can use the formula:
Distance = Speed x Time
Since the two trains are moving in opposite directions, their distances will add up to the total distance apart. Let's assume the time it takes for the two trains to be 363 miles apart is "t" hours.
For the first train traveling at 56 mph, the distance it covers in "t" hours is 56t miles.
For the second train traveling at 52 mph, the distance it covers in "t" hours is 52t miles.
Adding these two distances together will give us the total distance:
56t + 52t = 363
Now, you can solve this equation to find the value of "t".
