Rate = distance x Time question!

Question

Two spaceships separate from their space station at the same time and travel in opposite directions. The first ship moves at 82,000 km/h and the second at 43,000 km/h. In how many hours will they be 1,000,000 kilometers apart ?

Answer 1

The distance between the spaceships can be expressed as the following equation:

d = 82,000*t + 43,000*t

where d is the distance in kilometers and t is the time in hours after they left the space station. To find our answer, we must solve for the time t when d = 1,000,000. So, we rewrite our equation as:

1,000,000 = 82,000*t + 43,000*t

Next, we need to simplify:

1,000,000 = (82,000 + 43,000)*t

1,000,000 = 125,000*t

Now we have a nice, straightforward equation to solve!

Answer 2

82000t + 43000t = 1000000

125000t = 1000000

Can you calculate t and answer?
