Question

a cheetah can cover 50 yards in 5/2 seconds how long will it take a cheetah at the same speed to run 80 yards

Answer 1

I woud make that fraction a decimal. 5/2= 2.5
It takes 2.5 seconds to cover 50 yards. We need to do y/x to find the rate, or yards/time.
50÷2.5= 20
The cheetah covers 20 yards every second. We can find how many sets of 20 yards are in 80 yards to find the number of seconds.
80÷20= 4 × 1 = 4
It would take 4 seconds for the cheetah to run 80 yards.

Answer 2

I think it is 8.32 because I got 5/2 divided it by 50 to see how much it is running at 1 yard then multiplied by 80
