Jaime has 8/10 of a candy bar left over. He wants to split it into 1/3 pieces.
Valentin [98]

Answer:

2 pieces.

Step-by-step explanation:

To identify how many pieces he can split with 8/10 of a candy bar, divide 8/10 by 1/3.

<u>Divide 8/10 by 1/3:</u>

\frac{8}{10} / \frac{1}{3}=

<u>Find the Ricipricol, then flip the sign:</u>

\frac{8}{10} (\frac{3}{1} )=

<u>Multiply:</u>

<u />\frac{8}{10} (\frac{3}{1})=\frac{24}{10} =\frac{2.4}{1}

2.4 represents how many pieces of chocolate he can make with 8/10 of a candy bar.

However, 2.4 pieces can't be made, therefore he can only make 2 <u>full</u> pieces.

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
