The average distance from Earth to the Moon is 384,000 km.
Fofino [41]

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
