Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other
, their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours
Answer:
C) 0 <\ x OR x />7
Step-by-step explanation:
The first arrow has a closed circle which indicates greater/less than or equal to. All the values shaded are to the left of 0. So, <em>x</em> is less than or equal to 0. The second arrow also has a closed circle. Since the shaded part of the arrow is to the right of 7, <em>x</em> is greater than or equal to 7.

Answer:
Neither
Step-by-step explanation:
For two lines to be parallel, they must have the same slope. 2 and -2 are not the same. For lines to be perpendicular, their slopes must be negative reciprocals (ex 5 and -1/5) The slopes of these lines are not the same or negative reciprocals, so they are not parallel or perpendicular.
