Question

The average distance from Earth to the Moon is 384,000 km.
How many hours would it take, traveling at 800 kilometers per
hour (km/h)—the typical speed of jet aircraft—to reach the
Moon? How many days is this? How many months?

Answer 1

Answers:

1) Time it takes to travel to the moon

Velocity $V$ is defined as:

$V=\frac{d}{t}$

Where:

$d=384,000 km$ is the average distance from Earth to the Moon

$V=800 km/h$ is the velocity of the spacecraft

$t$ the time

Isolating $t$:

$t=\frac{d}{V}$

$t=\frac{384,000 km}{800 km/h}$

$t=480 h$ This is the time in hours

2) Time in days

A day is equivalent to 24 hours:

$1 day= 24 h$

Hence:

$t=480 h (\frac{1 day}{24 h})$

$t=480 h (\frac{1 day}{24 h})=20 days$ This is the time in days

3) Time in months

A month is equivalent to 30.4 days:

$1 month= 30.4 days$

Hence:

$t=480 h (\frac{1 day}{24 h})$

$t=20 days (\frac{1 month}{30.4 days})=0.65 months$ This is the time in months
