The distance from Earth to Mars is 136,000,000 miles. A spaceship travels at 31,000 miles per
hour. Determine, to the nearest day, how long it will take the spaceship to reach Mars.

Respuesta :

136,000,000/31,000= how many hours for the spaceship to reach mars
136,000,000/31,000/24= how many days for the spaceship to reach mars
136,000,000/31,000/24 is approx. 182.7 days or 183 days (rounded up b/c of "to the nearest day").

It will take the spaceship 183 days to reach Mars.

Since distance, d = vt where

  • v = speed and
  • t = time,

Making t subject of the formula, we have

t = d/v

Since

  • d = distance from Earth to Mars = 136,000,000 miles,
  • v = speed of spaceship = 31,000 miles per hour and
  • t = time it takes spaceship to reach Mars.

Substituting the values of the variables into the equation, we have

t = d/v

t = 136,000,000 miles/31,000 miles per hour

t = 4387.1 hours

We convert this to days

t = 4387.1 hours × 1 day/24 hours

t = 182.8 days

t ≅ 183 days to the nearest day.

So, it will take the spaceship 183 days to reach Mars.
