Answer:
1.5 hours
Step-by-step explanation:
we know that
1) Martha can paint a room in 2 hours
so
Martha can paint the 100% of the room in 2 hours
Find out what percentage of the room she can paint in an hour
using proportion
2) Jamie can paint a room in 6 hours
so
Jaimie can paint the 100% of the room in 6 hours
Find out what percentage of the room she can paint in an hour
using proportion
3) In one hour Martha and Jamie can paint
so
using proportion
Find out how long will it take them to paint the 100% room together
