In an ordinairy year, there are 365 days. in a leap year there are 366 days. there are 24 hours in a day. how many more hours are there in one leap year than in one ordinary year?

24 hours more in a leap year than in an ordinary year

Step-by-step explanation:

A leap year only adds one extra day so add an extra 24 hours

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
