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 

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

what do you get for the range of distance and speed?
Answered by Yip
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)
