These are two verbal problems, I don't know whether they're written grammatically.

1. At the request of plan, a factory would make 1500 products within 30 days. But owing to arranging work rationally, the factory outdid 15 products per day in fact. Therefore, the factory didn't only exceed the production norm 225 products but also fullfil the plan before the schedule.
How many days did the factory shorten?

2. A motor-cyclist went from A to B at the speed of 25 km/h. When returning, he went at the speed of 30 km/h so the backward time is less than the forward one 20 minutes.
Evaluate the distance AB

Thank in advance.
