The distance to the nearest 100,000 km from the earth to the moon is given as 400,000 km. The average speed to the Nearest 500km/h is 3500km/h. Calculate the least and greatest time it takes the rocket to reach the moon

Question

I figured out the formula speed = distance / time but none of these numbers and giving me the answers like my textbook which are 93.3and 138.5

Answer 1

what do you get for the range of distance and speed?

Answer 2

Distance : 350000km < 4000000km < 450000km(to the nearest 1000000km)

Average speed : 3250km/h < 3500km/h < 3750km/h(to the nearest 500km/h)

Since, Time = Distance/Speed.

Therefore, least time = 350000km / 3750km/h (lower bound)
greatest time = 450000km / 3250km/h (upper bound)

Answer 3

Fay, your answer is right.
