Jacob is calculating the amount of time it takes a rocket to get to the moom

16 hours

Step-by-step explanation:

Speed=distance/time

Let S be speed, D be distance, and t be time.

Let's solve the speed equation for t since we are looking for time, t.

Multiply both sides by t:

Divide both sides by S:

So our distance is 239000 and our speed is 250 so plug them in:

Putting into the calculator now:

t=956 minutes (I knew this was in minutes because the speed was 250 miles per minute)

We need to convert this to hours.  60 minutes=1 hour.

60 minutes=1 hour

956 minutes=x hours

You can setup a proportion if you don't know you just need to take 956 and divide it by 60.  Like so:

Cross multiply:

Divide both sides by 60:

Putting into calculator now:

x=15.9333333333333 which mean we have almost 16 hours
