Answer:
|-4|, |-4 1/4|, 4 1/2, 4 3/4
Step-by-step explanation:
The absolute value lines, | |, make the value inside of them positive. For example, the absolute value of -2 is 2. In this example, although -4 and -4 1/4 become positive, they are still lower than 4 1/2 and 4 3/4.
Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train
