A car moves at a speed that allows it to move 45 yards in 5/4 of a second. How
long will it take a car at the same speed to move 80 yards? Write your answer as
a fraction of a second.
of a second

Answer 1

To find the time it will take for the car to move 80 yards at the given speed, set up a proportion and solve for x. The car will take 20/9 of a second to move 80 yards.

Step-by-step explanation:

To find the time it will take for the car to move 80 yards, we can set up a proportion using the given information.

45 yards is to 5/4 of a second as 80 yards is to x.

Using cross multiplication, we can solve for x:

1. (45)(x) = (5/4)(80)
2. 45x = 100
3. x = 100/45

Simplifying 100/45, we get x = 20/9. Therefore, it will take the car 20/9 of a second to move 80 yards at the same speed.
