Answer:

6 sec

Step-by-step explanation:

Let d = distance for Jabal

d + 15 = distance for Michael

t = d/r

d/2.5 = time for Jabal

(d + 15)/5 = time for Michael

The times are equal since they both started walking at the same time.

(d + 15/5 = d/2.5

2.5(d + 15) = 5d

2.5d + 37.5 = 5d

37.5 = 2.5d

d = 15 m. = Jabal's distance

15/2.5 = 6 sec.

It takes 830 bricks to construct a wall that measures 14 feet 9 inches long and 6 feet high. The crew you hire can lay 300 brick
Yakvenalex [24]

Answer: B.) $1,383.53


Step-by-step explanation:

Given: The total number bricks required to make the wall= 830

The speed of crew= 300 bricks/hour

Total hours they take to make the wall= \frac{830}{300}\ hours

The cost of labour =$4,000 per eight-hour

⇒The cost of labour for 1 hour = \frac{\$4000}{8}=\$500

Now, the cost of wall= \frac{830}{300}\times500=1383.53

Hence, B is the right answer, the cost of the new wall= $1383.53
