The peregrine falcon has been measured as Traveling up to 350 km/hr in a dive. if this falcon can fly to the moon at this speed,
soldi70 [24.7K]

Answer:

4 × 10⁶ sec

Explanation:

The distance between the earth and the moon = 384,400 km

The speed of the peregrine falcon = 350 km/hr

Considering,

Distance = Speed × Time

So,

Time = Distance / Speed = 384,400 km / 350 km/hr = 1098.28571 hrs

Also,

1 hr = 3600 sec

So,

1098.28571 hrs = 3600 × 1098.28571 s ≅ 4 × 10⁶ sec

<u>Thus time taken by peregrine falcon if falcon fly to the moon = 4 × 10⁶ sec </u>
