Question

X = t^2-4t+5
Find distance covered in 3 second ​

Answer 1

Step-by-step explanation:

for finding distance covered in 3 seconds put t=3 in above equation.

x= (3)²-4(3)+5

x= 9-12+5

x=2 units.

Answer 2

$x = {t}^{2} - 4t + 5 \\ substituting \: t = 3 \\ {3}^{2} - 4 \times 3 + 5 \\ = 9 - 12 + 5 \\ = - 3 + 5 \\ = 2$
