is the correct answer

Answer 2

Given,

• s = 200km
• t = 10 seconds

To Find,

• The Speed

Solution,

1km = 1000m

200km = 200 × 1000m

200km = 2,00,000m

200km = 2 × 10⁵m

Speed = Distance/Time

Speed = 2 × 10⁵m/10 seconds

Speed = 2 × 10⁴ m/s

Required Answer,

If Distance = 200km

And Time = 10 seconds

Then,

Speed = 2 × 10⁴ m/s
