Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56

3,000 pounds of sand is usede to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?

Answers

500pounds because 2000 (the left over sand after you fill the big box) divided by 4(smaller sandboxes) is 500

The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

What is division?

Division is breaking a number up into an equal number of parts.

Given that, 3,000 pounds of sand is used to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes.

Amount left after filling the larger box = 3000-1000 = 2000 pounds

To find the equal amount of sand to be filled in 4 smaller boxes, we will divide the amount left to the number of boxes.

= 2000/4

= 500

Hence, The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.
