10 trees    in 2 hours  = 5 trees per hour

150 trees * 1 hour/ 5 trees =  30 hours

30 cars in 5 hours  = 6 cars per hour

120 cars * 1 hour/6 cars = 20 hours

it will take 20 hours to wash 120 cars.

25 letters per minute * 5 minutes = 125 letters

15000 phones per hour

300000 phones * 1hour/15000 phones = 20 hours

375 ft^2/ 15 min =  25 ft^2/min

It will take 30 hours to plant 150 trees
