Question

A spacecraft is traveling at a speed of 2.3 km/sec. It takes 2.5 minutes to pass a small asteroid. how wide is the asteroid (i.e., how far did the spacecraft travel during this time)? Use (distance) = (velocity) x (time)

Answer 1

Answer: The spacecraft traveled 345 km during the given time.

Explanation:

To calculate the distance of spacecraft, we use the equation:

$\text{Velocity}=\frac{\text{Distance}{\text{Time}}$

We are given:

Velocity = 2.3 km/sec

Time = 2.5 mins = 150 sec             (Conversion factor: 1 min = 60 sec)

Putting values in above equation, we get:

$\text{Distance}=(2.3km/s\times 150s)=354km$

Hence, the spacecraft traveled 345 km during the given time.
