How long would it take to travel 425 m at the rate of 50 m/sm/s ?

8.5 s

375 s

475 s

21,250 s

pl no

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 =

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 =

50 =

Cross -multiply

50 t = 425

Divide both-side of the equation by 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

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
