Step-by-step explanation:

Answer 2

Answer: c. 2.8 hours, yes

Step-by-step explanation:

Robert needs to travel 500 miles at a rate of 180 miles per hour. That means that we need to find how many hours that would take.

Then:

500 = 180*x

x is the number of hours that he needs for the journey

Then:

500/180 = x hours

500/180: 2.8 hours

Considering that it takes less than three hours to get to his mother´s birthday, if Robert leaves at 2 pm he will arrive around 5 pm, with plenty of time to get to the party at 8 pm.
