Answer: Elise ran faster.
Explanation:
Elise 2 mi in 15 min
Tengan 3 km in 15 min
We need to covert the miles (mi) or kilometers (km) so that they are both the same. You should know that 1 mi = 1.6 km. After you convert the measurements, you can compare. Since they both are measured in minutes, you don't have to worry about that, but if they aren't you should convert it one or the other, so that they are the same.
2 mi = 3.2 km (Elise)
3 km (Tengan)
Elise is 0.2 faster than Tengan.
