The answer to your questions is A 8.5 s

Hope this helps!!

Answer:

8.5 s

Step-by-step 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 = \(\frac{d}{t}\)

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 = \(\frac{d}{t}\)

50 = \(\frac{425}{t}\)

Cross -multiply

50 t = 425

Divide both-side of the equation by 50

\(\frac{50t}{50}\)  =  \(\frac{425}{50}\)

(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
