Question

Item 3
Joel digs a hole at a rate of 3/5 feet every 10 minutes. After digging for 30 minutes, Joel places a bush in the hole that fills exactly 1/2 feet of the hole.

Relative to ground level, what is the elevation of the hole after placing the bush in the hole?

Enter your answer as a simplified mixed number in the box.

ft

Answer 1

The elevation in feets of the hole after digging and filling the hole with bush is $1 \frac{1}{10} \: feets$

Digging rate = 3/5 feets per 10 minutes

Elevation or depth of hole after 30 minutes :

3/5 × (30/10) = (3/5 × 3) = 9/5 feets

Therefore, the elevation of the hole after 30 minutes will be 9/5 feets

Elevation after filling half of the hole with bush :

Elevation of hole after 30 minutes ÷ 2

(9/5) ÷ 2 = 9/5 × 1/2 = 9/10 feets

Hence, the elevation of the hole relative to the ground level is $1 \frac{1}{10}$
