To determine how long Morag took to run 15 kilometers at an average speed of 6 kilometers per hour, follow these steps:
1. Calculate the total time taken in hours:
To find the total time taken, divide the distance by the speed.
\(\[
\text{Time (hours)} = \frac{\text{Distance (km)}}{\text{Speed (km/hr)}}
\]\)
Substituting the given values:
\(\[
\text{Time (hours)} = \frac{15 \text{ km}}{6 \text{ km/hr}} = 2.5 \text{ hours}
\]\)
2. Convert the time into hours and minutes:
We now need to convert 2.5 hours into hours and minutes.
- The whole number part (before the decimal) represents the hours. In this case, it is 2 hours.
- The decimal part (0.5) needs to be converted into minutes.
3. Convert the decimal part into minutes:
To convert 0.5 hours to minutes, multiply by 60 (since there are 60 minutes in an hour).
\(\[
0.5 \times 60 = 30 \text{ minutes}
\]\)
Therefore, the time taken by Morag to run 15 kilometers at an average speed of 6 kilometers per hour is 2 hours and 30 minutes.
