Question

You are leaving for a party at your cousin’s house in a city that is 150 km away. You will travel at an average rate of 50 km/hr. How long will it take you to arrive?

Answer 1

To answer this question, simply divide the total distance by the average rate of 50 km and you should be left with hours if you use dimensional analysis.

`=150\ km` ×
`(1\ hour)/(50\ km)`

= 3 hours

Answer 2

Step-by-step explanation:

Hi there!

From the question,

Distance (d) = 150km

Average rate (s) = 50km/hr

Time (t) = ?

Now,

Average rate (s) =
`(Distance (d))/(Time(t))`

50 =
`(150)/(t)`

50 t = 150

Therefore, it will take 3 hours to arrive.

Hope it helps!
