The distance to the nearest 100000 km from Earth to the moon is given as 400000 km.The average speed to the nearest 500 km/h of a rocket to the moon is given as 3500 km/h.Calculate the greatest and least time it could take the rocket to reach the moon.

To calculate the greatest and least time it could take the rocket to reach the moon, we need to divide the distance between Earth and the moon by the average speed of the rocket.

Let's start with calculating the greatest time it could take. We divide the given distance (400,000 km) by the lowest average speed (3,500 km/h) to get:

400,000 km / 3,500 km/h = 114.286 hours (rounded to 3 decimal places)

So, the greatest time it could take for the rocket to reach the moon is approximately 114.286 hours.

Now let's calculate the least time it could take. We divide the same distance (400,000 km) by the highest average speed (3,500 km/h) to get:

400,000 km / 3,500 km/h = 114.286 hours (rounded to 3 decimal places)

So, the least time it could take for the rocket to reach the moon is also approximately 114.286 hours.

Thus, the greatest and least time it could take the rocket to reach the moon is approximately 114.286 hours.
