Question

Mr. Tram was planning his trip from Dallas, TX to Detroit, MI. He knows that the total distance he needs to cover is 1620 km. He usually drives at a speed of 60 km per hour. B If he is willing to drive up to 8 hours per day, how many days will this trip take?

Answer 1

4 days

Explanation:

If he drives 60 km an hour and drives 8 hours a day, he can drive (60*8 = 480)

480 km in a day.

If the total distance is 1620 km and he drives 480 km a day (1620/480 = 3.375) it would take him four days to take his trip. You have to round up to 4 in this scenario. You can't round down because in three days he'd only have traveled (480*3 = 1440) 1440 km. If you even drive for a second on the fourth (3 < x < 4) day, then the trip "took" four days.

Answer 2

~ 3 1/2 days

Explanation:

Mr.Tram travels at a constant speed of 60 km per hour, and travels for up to 8 hours per day (max). Multiply 8 with 60:

60 x 8 = 480

Next, divide 480 from 1620 to get the amount of days:

1620/480 = 3.375

~ 3 1/2 days is how long Mr.Tram will take to travel from Dallas, TX to Detroit, MI.
