Answer 1

Hey friend!!!

Here is your answer..

⬇️⬇️⬇️⬇️⬇️⬇️

$v = 2520 \: km {hr}^{ - 1} \\ v = 700 \: m {s}^{ - 1} \\ \\ v = u + at \\ 700 = a \times 0.2 \\ a = 3500 \: m {s}^{ - 2} \\ \\ now \\ \\ s = ut + \frac{1}{2} a {t}^{2} \\ s = \frac{1}{2} \times 3500 \times 0.2 \times 0.2 \\ s = 70m$

HOPE that it will help you ✌️ ✌️

Answer 2

Answer:

Step-by-step explanation:

Speed = distance / time

Distance = speed x time

d = 2520000 x 0.2 = 504000m

Therefore distance = 504000m = 540km
