Question

If I am traveling 104 kilometers per hour and need to travel 141.8 kilometers how long would I be traveling for? Thx.

Answer 1

1 hour 22 minutes

Explanation:

You travel 104 kilometres in one hour so now you want to find how long it takes for you to travel 141.8 kilometres.

One way you can think of it is:

104km = 60 minutes (1hour) so 141.8km = ?

time taken = `(141.8times60)/104 = 81'48'`

So you would take about 81 minutes 48 seconds to travel 141.8km which you can round to 82 minutes. Therefore, you would take about 1 hour 22 minutes.

Another way you can do it is if you find how long it would take you to travel 1km

ie time taken = `60/104 = 34 "secs"`

Then you go since you take 34 secs to travel 1 km, 141.8km would take you `141.8times34 = 81'48'`. So same answer as the first way.
