A racecar is traveling at a constant speed of 120 miles per hour. How many feet does it travel in 6 seconds? Remember that 1 mile is 5280 feet.

1056 ft

Step-by-step explanation:

We need to convert the units from miles per hour to feet per second:

recall that i mile = 5280 ft, and one hour is 3600 seconds, so we do the conversion of the 120 miles per hour speed as follows:

which means that the car cover 176 ft in one second. Therefore, in 6 seconds it will cover 6 times this:

distance = 176 * 6 = 1056 ft

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
