time=distance/speed
if speed is given in ml per hour then:
time=410/120=3.417 hours=3 hours 25 min
plus half an hour totally for stops.
total time will be 3 hours 55 min.
if speed is given in km per hour you have to convert to ml per hour 1st:
1 km = 0.62 ml
120 km/hr = 120*0.62 ml/hr.
then follow the same strategy =)
The first thing to notice about this problem is that you have a mixture of Metric and English units. The first thing that I would recommend is to convert 410 miles into Kilometers
1 mile = 1.61 km
410 miles = (410*1.61) = 660 km (rounded to the nearest km)
Now you need to know the time. The formula for travel is d=rt. You know the distance, and you know the rate, solve the formula for time.
t=d/r.
t=660km/120km/k
t=5.5 hours. Plus add the 2 15 minutes breaks. 2*15=30 minutes. 60 minutes in an hour means that you add 30/60 hours to the trip, or another .5 hours.
Therefore the answer is 5.5+.5 hours.
The answer is: time=6 hours.
