Answer:
46 minutes.
Step-by-step explanation:
Running 2 km in 13 minutes translates to 6 minutes and 30 seconds per km.
minutes: 6 x 7 = 42
seconds: 30 x 7 = 210
second part: 210/60 = 3 minutes 30 seconds
adding everything together: 42 minutes + 3 minutes 30 seconds + 45 minutes 30 seconds, rounded equals 46 minutes
In part one, the scale states that 1 on the map correlates to 100,000 in reality. Therefore, a distance of 12 cm on the map translates to (12 cm)(100,000) in real terms, giving us 12 cm equating to 1,200,000 cm. Since each meter equals 100 cm, thus the real distance is calculated as 1,200,000 cm divided by 100 cm/m, resulting in 1,200 m. Further, this equals 1.2 km when converted to kilometers. In the second part, the scale shows 1 on the map corresponding to 300,000 in the real world. So, 12 cm on this map translates to (12 cm)(300,000), resulting in 12 cm equating to 3,600,000 cm. As before, dividing this by 100 cm/m gives 3,600 m, and converting this to kilometers results in 3.6 km. Notably, 300,000 is three times 100,000, suggesting that the real distance here is also tripled in comparison, with the first scenario being 1.2 km and the second being 3.6 km, giving the final answer as 3.6 km, 3,600 m, or 3,600,000 cm.
