Chance can wash the car in 2 hours, while Sandy can wash the same car in 4 hours. How many hours would it take for them to wash

aliya0001 [1]

Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

Number of hours Chance can wash the car = 2 hours

Number of hours Sandy can wash the car = 4 hours

Work done by Chance per hour is given by

$\frac{1}{2}$

Work done by Sandy per hour is given by

$\frac{1}{4}$

Work done by altogether per hour is given by

$\frac{1}{2}+\frac{1}{4}\\\\=\frac{2+1}{4}\\\\=\frac{3}{4}$

So, Number of hours they take if they together wash the car is given by

$\frac{4}{3}$

Hence, First Option is correct.
