Answer:

It will take 6.5 hours for Evan's sister to catch up to Evan.

Step-by-step explanation:

Given that Evan left Minneapolis heading east on the interstate at a speed of 55 mph, and his sister followed him on the same route, leaving half an hour later and driving at a rate of 65 mph, to determine how long will it take for Evan's sister to catch up to Evan the following calculation must be performed:

Hour 1 = 55

Hour 2 = 110 /// 65

Hour 3 = 165 /// 130

Hour 4 = 220 /// 195

Hour 5 = 275 /// 260

Hour 6 = 330 /// 325

Hour 7 = 385 /// 390

Time 6.5 = 357.5 /// 357.5

Therefore, it will take 6.5 hours for Evan's sister to catch up to Evan.
