Arada [10]

Answer:

The time required them working together to shovel the snow is T = 1.428 hours

Step-by-step explanation:

Given data

Time taken by first person to shovel the snow $T_1$ = 2 hours

Time taken by second person to shovel the snow $T_2$ = 5 hours

Time taken by both persons to shovel the snow

$\frac{1}{T} = \frac{T_1+T_2}{ (T_1) (T_2)}$

Put all the values in above equation we get

$\frac{1}{T} = \frac{2 +5}{(2)(5)}$

T = 1.428 hours

Therefore the time required them working together to shovel the snow is T = 1.428 hours
