Who spends 2/3 of his money on a video game before spending half of his remaining money on lunch if his lunch cost $10 how much money did he have at first

2/3 on video games

1/3 left

1/3 x 1/2 = 10 (half of 1/3 is $10)

= 1/6 of the whole

1/6 x 10 = 60

Therefore, you have $60 at first

We have to work backwards for this. Since his lunch came at $10 and it says half of his remaining money, this means that $10 was half and the real value was $20. Now since he spent 2/3 of his money on video games, this means that $20 is only 1/3 of that, so we multiply by 3 and we get the original amount of $60.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
