Eli is driving at a speed of 66 miles per hour. Let h represent the number of hours Eli drives at this speed. Write an algebraic expression to represent the number of miles that Eli travels during this time.

Since distance = time x rate

number of miles = 66h

To find the number of miles Eli travels, we can use the formula distance = speed × time.

Let's call the distance Eli travels "d" and the number of hours he drives "h". Since Eli is driving at a speed of 66 miles per hour, we can write the formula as:

d = 66h

Therefore, the algebraic expression to represent the number of miles Eli travels is 66h.
