Train A is traveling 15 miles in 1 minute. Train B is traveling 90 miles in 5 minutes. Both trains are moving at a constant speed. Are they both going the same speed?

No

Step-by-step explanation:

Find their speeds by dividing the number of miles by the minutes:

Train A:

15/1

= 15 miles/minute

Train B:

90/5

= 18 miles/minute

So, since 15 and 18 are not equal to each other, they are not going at the same speed.

Train B is going faster than Train A.

So, they are not both going at the same speed

the answer is (-4,-4)
