Let x= the usual speed
1500/x would equal how long it usually took the plane to read the destination
1500/(x+100) would equal how long it would take the plane now
So

because it would lose 30 minutes already
Simplify:





The usual speed was 500 hm/hr
Answer:
Graph would be the most reasonable.
Step-by-step explanation:
Hope I helped, good luck!<3!!
16x+3y=251 and 8x+4y=148 then you set them up to each other and cancel one coefficient through elimination or find out what X or Y equals and substitute into either equation
Answer:
1 is a increase
2 is decrease
