A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same

pickupchik [31]

Answer:

First, remember the relation:

Distance = Speed*Time.

We know that the distance is 120mi.

A) For the biker we know that:

Time = 8hours.

Speed = Distance/Time = 120mi/8h = 15 mi/h.

B) For the bus we know that:

Time = 2 hours.

Speed = Distance/Time = 120mi/2h = 60 mi/h.

C) For the truck we know that:

Time = 2.5 hours.

Speed = Distance/Time = 120mi/2.5h = 48 mi/h.

D) For the rider on a horse we know that:

Time = 18.75 hours.

Speed = Distance/Time = 120mi/18.75h = 6.4 mi/h.

E) The equation for the speed is:

Speed = Distance/Time.

You can see that time is in the denominator, this means that if for a fixed distance, the time increases, then the denominator increases, which would imply that the speed decreases.

Then the speed is inversely proportional to the time when the distance is fixed.

Jack buys a bag of 5 apples each equal in size he eat 1/2 of one Apple what fraction did he eat

Karo-lina-s [1.5K]

You have $4\frac{1}{2}$ apples left.
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate $\frac{1}{2}$ of it.
Jack ate $\frac{1}{2}$ of an apple in 5 apples.
If you say that Jack ate $\frac{1}{2}$ of 3 apples, then he ate $1\frac{1}{2}$ apples. So there isn't any difference when he ate $\frac{1}{2}$ of an apple.

In a game a die numbered 9 through 14 is rolled. What is the probability that the value of a roll will be a multiple of two or t

Marysya12 [62]

Answer:

Step-by-step explanation:

This is a special die. Its six sides bear the numbers {9, 10, 11, 12, 13, 14}.

There are three possibilities for getting a multiple of two: {10, 12, 14}, and

there is only one possibilities for getting a multiple of ten: {10, 12, 14}

The probability here of getting a multiple of two is 3/6, and that of getting a multiple of ten is 1/6. But one of the outcomes is found in both result sets: 10. Getting a multiple of 10 is already included in the event that the outcome is a multiple of two. My answer here would be 3/6, or 1/2.
