An jet travels at a constant speed of 320 miles per hour. How far, in miles, will the jet travel in 15 minutes?

80 miles. Step-by-step explanation: If it is traveling at 320 miles per hour, and its asking how much its traveled in 15 minutes you do this: Since 15 minutes is 1/4 of an hour, you take 1/4 of how fast they are traveling at mph, which in this case is 320 mph

80 miles

Step-by-step explanation:

15 minutes  = 1/4 hour

distance = speed * time

d = 320 * 1/4

d = 80 miles

40=6 miles
20=3 miles
1:20=12 miles
2:20=21 miles
10min =1.5 miles
1:40=15 miles
