Given that Ronald's average running speed per second, determine the distance that he has ran in 30 minutes in metres.

Given: Ronald's speed: 1.9 metres per second or 1.9m/s^2

FInd: Distance he ran in 30 minutes

First. we have to convert the seconds to minutes, we can do this by multiply by 60. Since, there is 60 seconds in a minute.

60 x 1.9 = 114

That means, Ronald runs 114 metres in a minute, then we multiply by 30 to find out how many metres he runs in 30 minutes. So, we would multiply his speed per minute by 30.

30 x 114 = 3420

Thus, Ronald has ran 3,420 metres in 30 minutes.

If he continues at the same pace, he will have ran 6,840 metres in an hour.

3420 metres.

Step-by-step explanation:

30 minutes = 30 * 60 = 1800 seconds.

So the distance Ronald has run is 1800 * 1.9

= 3420 metres.

10% of increase is the final answer! : )
