Problema Solution
The speed of train A is 16 mph slower than the speed of train B. Train A travels 230 miles in the same time it takes train B to travel 310 miles. Find the speed of each train.
The speed of train A is ____ mph
The speed of train B is _____ mph
Answer provided by our tutors
A=B-16
A*t=230
B*t=310
so t=230/A
B*230/A=310
230 B=310 A
230 B= 310 (B-16)
230 B = 310 B - 310*16
80 B = 310 * 16
B= 31*2=62 mph
A = 62-16=46 mph
