Answer 1

Answer:

please give brainlist answer mark if you like it

Explanation:

How to calculate average speed. Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.

Answer 2

Answer:

mark me as brilliant

Explanation:

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this:

Speed = distance (60 km) / time (1 hour) = 60km/h.

Let’s take a more complex example: what’s the average speed if you covered 425.5km in 5 hours 22 minutes and 30 seconds?

Firstly, we have the problem again with the time not being decimalised. We can use the same method we did before:

30 seconds / 60 seconds is 0.5. This means 30 seconds is 0.5 minutes. Therefore we add that the 22 minutes and repeat it again:

22.5 minutes / 60 minutes = 0.375 hours. Add that onto the 5 hours and you have 5.375 hours.

Speed = distance (425.5km) / time (5.375 hours) = 79.16km/h
