8.5 s

375 s

475 s

21,250 s

plzzzzzzzzzzzzzzzzzzzz help nowwwwwwwwwwwwwwwwww

Answer 1

8.5 s

Explanation:

How long means time taken, so to find the time taken to travel 425 m at the rate of 50 m/s, we will simply use the formula below

V =
`(d)/(t)`

where v is the speed or velocity, d is the distance travelled and t is the time taken.

From the question given, distance (d) = 425 m, velocity/speed(v) = 50

We can now proceed to insert our values into the equation

V =
`(d)/(t)`

50 =
`(425)/(t)`

Cross -multiply

50 t = 425

Divide both-side of the equation by 50

`(50t)/(50)` =
`(425)/(50)`

(On the left-hand side of the equation 50 at the numeartor will cancel-out 50 at the denominator leaving us with just x, while on the right-hand side of the equation 425 will be divided by 50)

t = 8.5 sec.

Therefore the time taken is 8.5 s
