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
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
Simplify:
The usual speed was 500 hm/hr
