Answer 2

Calculation of Distance

To calculate the distance the skier will run in 1 hour and 30 minutes, we can use the information given: the skier ran 7 kilometers in 15 minutes.

First, let's calculate the skier's speed in kilometers per minute. We can do this by dividing the distance (7 kilometers) by the time (15 minutes):

Speed = Distance / Time = 7 km / 15 min.

Now, we need to convert the time of 1 hour and 30 minutes into minutes. Since there are 60 minutes in an hour, we can calculate the total time in minutes as follows:

Total Time = 1 hour * 60 minutes/hour + 30 minutes = 60 minutes + 30 minutes = 90 minutes.

Finally, we can calculate the distance the skier will run in 1 hour and 30 minutes by multiplying the speed by the total time:

Distance = Speed * Total Time = (7 km / 15 min) * 90 min.

Let's calculate the distance:

Distance = (7 km / 15 min) * 90 min = 42 km.

Therefore, the skier will run a distance of 42 kilometers in 1 hour and 30 minutes.

Please note that this calculation assumes a constant speed throughout the entire run and does not take into account factors such as fatigue or changes in speed.
