How long dose it take to travel 5km at an average speed of 8 m/s? Give your answers in minutes and seconds

eduard

Answer:

625 seconds and 10 minutes

Step-by-step explanation:

distancs=S=5km=5000m

average speed=v=8m/s

time taken=t=?

as we know that

average speed= $\frac{distance covered}{time taken}$

average speed×time taken=distance covered

here we have to find the time taken

time taken= $\frac{distance covered}{average speed}$

time taken= $\frac{5000m}{8m/s}$

time taken=625seconds

now we convert seconds into minutes

$\frac{625}{60}$

10 minutes

Given

arlik [135]

Answer:

a = 3, b = - 7

Step-by-step explanation:

Substitute x = 2 into the equation and equate to 5, that is

a(2)² + b = 5

4a + b = 5 → (1)

Substitute x = 3 into the equation and equate to 20

a(3)² + b = 20

9a + b = 20 → (2)

Subtract (1) from (2) term by term to eliminate b

(9a - 4a) + (b - b) = (20 - 5), that is

5a = 15 ( divide both sides by 5 )

a = 3

Substitute a = 3 into either of the 2 equations and solve for b

Substituting in (1)

4(3) + b = 5

12 + b = 5 ( subtract 12 from both sides )

b = - 7
