Walt and Amy each have the same number of pennies. Walt made equal stacks of 10 pennies with none left over. Amy made equal stacks of 8 pennies with none left over. What is the least number of pennies that each person could have? Explain how you found your answer.

Answers

Answer 1
Answer:

Answer:

40 coins

Step-by-step explanation:

Note that

10=\underline{2} \cdot 5,\n \n8=\underline{2} \cdot 2\cdot 2.

To find the least common multiple you have to multiply all common multiplies and then multiply them by all factors that left. Thus,

LCM(10,8)=\underline{2} \cdot 5\cdot 2\cdot 2=40.

This means that if Walt and Amy each have 40 coins, then Walt can make 4 stacks with 10 coins in each and Amy can make 5 stacks with 8 coins in each.

HELP PLZA biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. What are their speeds?

Answers

The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

What is speed?

Speed is the distance that a particle or body travels in one hour. It has a scalar value. It is the time-to-distance ratio.

We know that the speed formula

Speed = Distance/Time

A biker’s speed is 1.5 times faster than a walker’s speed.

Let y be the speed of the biker and x be the speed of the walker. Then the equation is given as,

y = 1.5x

They begin going simultaneously from the same location in the same direction, and after 1.5 hours, there are 12.5 miles separating them.

y - x = 12.5 / 1.5

1.5x - x = 25/3

0.5x = 25/3

x = 16.67 miles per hour

Then the speed of the biker will be given as,

y = 1.5 (16.67)

y = 25 miles per hour

The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.

Step-by-Step explanation:

Leave the speed of a walker alone x

Let the speed of a biker be 1.5x

They are moving a similar way,

thus, their Relative speed will be

1.5x - x =0.5x

Time taken = 1.5 hours

Separation between them = 12.5 miles

As we probably am aware the equation for "Distance":

*Picture attached*

Consequently, the Speed of the walker be 16.67 miles every hour

Speed of biker be

1.5 times 16.67=25 miles per houe
