Question #d41b3

Answer 1

distance=300,000 000meters/second.

Explanation:

300000000x498=149400,000,000 meters.
8.3 minutes=498 secocnds.

Answer 2

`~~1.498xx10^8` `kms`

Explanation:

Let's calculate it using the Speed Distance and Time formula

`color(blue)("Speed"="Distance"/"Time"`

So, the distance will be the product of the Speed and time take

Convert the time from minutes to seconds

`rarr8.3` `"mins"` `=498` `sec`

So the distance in metres would be

`rarr3xx10^8xx498` `m`

`rarr1498xx10^8` `m`

Write it in standard form

`rarr149800000000` `m`

To convert to kilometres cancel out the three `0's` at the end

`color(green)(rArr149800000=1.498xx10^8` `kms`

Hope this helps..! :)
