Water pool

A pool with a volume of 990 hl is completely filled if water flows from one tap for 8 hours and from a second tap for 6 hours. The first tap delivers 10 hl more per hour than the second. How many hl per hour does each tap deliver?

Final Answer:

a =  75 hl/h
b =  65 hl/h

Step-by-step explanation:

990 = 8 a + 6b a = 10 + b  990=8 a+6(a10)  990=8 a+6 (a10)  14a=1050  a=141050=75  a=75=75 hl/h
b=a10=7510=65 hl/h
