Question 832040: A jet boat can travel 50mph and a cargo boat travels at 24mph. A rig is 70 miles off the coast. A. If the two boats leave the coast at the same time, how far away from the oil rig will the cargo boat be when the jet boat reaches the rig? Nearest half mile. B. How much time will the repair crew have to fix the refrigeration system before the cargo arrives? Nearest half hour. Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! A. How long does it take for the jet boat to reach the rig?
70 miles/50 mph = 1.4 hours
In 1.4 hours, how far does the cargo boat travel?
1.4 hours * 24mph = 33.6 miles
Rounded to the nearest half mile = 33.5 miles.
.
B. How long does it take for the cargo boat to reach the rig?
70 miles/24 mph = 2.917 hours (that's rounded from a 6 that goes on forever)
What is the difference between 2.917 hours and 1.4 hours?
1.517 hours
Rounded to the nearest half hour = 1.5 hours
