Use this formula to calculate this word problem. d= r*t Robert is going on a trip to see his mother for her birthday party that evening, and is considering taking the train. His
mother lives 500 miles away, and he needs to work most of the day before he leaves. The train travels about 180 miles
per hour. How long will it take him to travel? If he leaves at 2PM, will he have enough time to get to the party at 8PM?
a 18.8 hours, yes
c. 2.8 hours, yes
b. 90 minutes, yes
none of the above
d.

c. 2.8 hours, yes

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.
