Materials 4405

Two trucks were supposed to load the building materials in 10 days. After 6 days of work, the first car broke down, and the second one carried building materials for another 9 days. How many days would the first and second cars take the building materials?

Correct answer:

a =  18 d
b =  22.5 d

Step-by-step explanation:

1/a+1/b = 1/10 6/a + (6+9)/b = 1 a=18=18 d
b=1/(1/101/a)=1/(1/101/18)=22.5 d
