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 = [tex]\frac{d}{t}[/tex]
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 = [tex]\frac{d}{t}[/tex]
50 = [tex]\frac{425}{t}[/tex]
Cross -multiply
50 t = 425
Divide both-side of the equation by 50
[tex]\frac{50t}{50}[/tex] = [tex]\frac{425}{50}[/tex]
(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
