Question

When people buy wood to burn in a stove they purchase it in units of cords ( stacks that are 128 cubic feet).Camilla had 3 cords of wood delivered and stacked. She noticed that the people stacking the wood could stack 3/10 of a cord in 2/5 of an hour. What is the rate they are stacking the wood in cords per hour?

Answer 1

Answer:

Step-by-step explanation:

Formula

r = amount / time

Givens

amount = 3/10

time = 2/5

Solution

r = 3/10 // 2/5

Invert the denominator (2/5) and multiply rather than divide.

r = 3/10 * 5/2    Cancel 5 into the 10

r = 3/2 * 1/2

answer: r = 3/4 chord / hour
