Question

Jose can paint an entire house in seven hours and brandon can paint the same house in eight hours. Write an equation that can be used to find the time in hours, t, it would take jose and brandon to paint the house together. You do not need to solve the equation.

Answer 1

t/8 + t/7 = 1

Explanation:

Given in the question that,

time require for Jose to paint the house = 7 hours

time require for Brandon to paint the house = 8 hours

Suppose t means Full house painted.

To solve the question we have to figure out how much each of them can paint in ONE hour.

7 hours----t

1 hour ---- t/7

8 hours----t

1 hour ---- t/8

Equation

t/8 + t/7 = 1 (in one hour)

(7t + 8t)/8(7) = 1

15t/56 = 1

15t = 56

t = 56/15

t = 3.73 hours
