1. 100 kilometers at 20 km/h?

2. 180 kilometers at 45 km/h?

Nonsense will be reported!!
Plss help me on this!! I Have Already get the answer but my friend said rwong!!​

Answer 1

1. 5 hours

2. 4 hours

Reason:

Formula for speed is speed =
`(distance)/(time)` , if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.

Answer 2

`\\ \rm\hookrightarrow Speed=(Distance)/(Time)`

`\\ \rm\hookrightarrow Time=(Distance)/(Speed)`

So

#1

`\\ \rm\hookrightarrow Time=(100)/(20)=5h`

#2

`\\ \rm\hookrightarrow Time=(180)/(45)=4h`
