Trains a and b are 240 miles apart. both start at the same time and travel toward each other. they meet 3 hours later. the speed of train a is 20 miles faster than train b. find the speed of each train.

Step-by-step explanation:

240 divided by 3 = 80

80 divided by 2 = 40 = train b speed

40+ 20 = 60 = train a speed

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
