Je suis un nombre entier compris entre 809 et 829. Je suis dovisible par 2 et 3, mais pas par 4 ni par 9. Qui suis-je?

Je suis 822.

Step-by-step explanation:

The required number must be divisible by 2,  so it will be even and  as it is also divisible by 3, the sum of its digits will be a number divisible by 3.

So the number could be one of the following:

810, 816, 822. 828.

810 is divisible by 9.

816 is divisible by 4.

822 is not divisible by 4 or 9.

828 is divisible by 4.

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
