John has $2 in nickels and dimes in his drawer. the number of nickels is three times the number of dimes. how many of each are in the drawer?

The number of nickles in drawer is 20  and

The number of dimes in drawer is 10  

Step-by-step explanation:

Given as :

Total money in nickels and dimes = $ 2

Let The number of nickels = n

And The number of dimes = d

According to question

The number of nickels is three times number of dimes

I.e  n = 3 times d

Or ,  n = 3 d

∵  n + d = $ 2

and 20 nickles = 1 dollar

      10 dimes = 1 dollar

So, 20 nickles + 10 dimes = $ 1 + $ 1

or, 20 nickles + 10 dimes = $ 2

So, number of nickles is 20, and number of dimes is 10

Hence The number of nickles in drawer is 20  and

The number of dimes in drawer is 10   answer

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
