A remote control car races straight down the street at 26 miles per hour. Two

Pachacha [2.7K]

Answer:

It will take 4 hours for the second car to catch up with the first car.

Step-by-step explanation:

The first step to solving this problem is determining the difference in speed between the first and second car - you can see that the second car (at 52mph) is twice as fast as the first (26mph) therefore it will take half the time to cover the same distance.

As Car 1 has a 2 hour head start, it will be 52 miles ahead after 2 hours.

In the next 2 hours, Car 1 will travel 52 miles - so 104 in total after 4 hours, and car 2 will travel 104 miles, meaning that it will have caught up after 4 hours.

A)

To calculate distance per minute, divide the miles per hour by 60 (as there's 60 minutes in an hour), so:

Car 1 = 26/60 = 0.43 miles per minute

Car 2 = 52/60 = 0.867 miles per minute

To check your calculation, Car 2 should be exactly twice as far

B) The street, as far as we know, is at least 104 miles

C) See calculation at the top - the first car is 52miles from the start line when the second car starts

D) 2 cars are competing in this race

finlep [7]

Question:

Aubrey has a new art box in the shape of a rectangular prism. The box is 5 inches by 8 inches by 2 inches. The only thing in the art box is a new pink eraser with the dimensions shown below.

0.25 inches by 1 inches by 2 in ches

What is the volume of the art box not taken up by the eraser?

Answer:

$Volume = 79.5in^3$

Step-by-step explanation:

Given

$Box = \{5in, 8in, 2in\}$

$Eraser = \{0.25in, 1in, 2in\}$

Volume is calculated as:

$Volume = Length * Width * Height$

First, we calculate the volume of the box:

$V_{box} = 5in * 8in * 2in$

$V_{box} = 80in^3$

Next, we calculate the volume of the eraser.

$V_{eraser} = 0.25in * 1in * 2in$

$V_{eraser} = 0.5in^3$

The volume not taken up is calculated as thus:

$Volume = V_{box} - V_{eraser}$

$Volume = 80in^3 - 0.5in^3$

$Volume = 79.5in^3$
