Answer:
36
Step-by-step explanation:
6 x 6 = 36
now to the nearest tenth it would be
36
so your answer is 36
PART 1.
Going westward:
Distance: 2400 miles
Rate (this is speed): (450-wind_speed) mph
Time: distance / speed = 2400 / (450-wind speed)
Going eastward:
Distance: 2400 miles
Rate (this is speed): (450+wind_speed) mph
Time: distance / speed = 2400 / (450+wind speed)
PART 2
Formula for speed:
speed = distance / time
Now we solve this for time:
time = distance / speed
11h = 2400 / (450+-wind_speed)
+- sign is put because in one case wind increases speed of plane and in other case it decreases speed.
PART 3
To solve for wind_speed we start by rearranging formula so that we have wind_speed on left side:
(450+-wind_speed) = 2400 / 11
(450+-wind_speed) = 218mph
To fly this distance in 11h speed of plane must be 218mph.
The only way to get this solution is if we substract wind speed:
450-wind_speed = 218
wind_speed = 450-218 = 232mph
Answer:
Step-by-step explanation:
- Time in New York = noon = 12:00 PM
- Time in Denver = 10:00 AM
Time difference = -2 hours
- Train departs at 2:00 PM
- Travel time = 45 hours
<u>Train arrival time:</u>
- 2:00 PM + 45 hours = 2:00 PM - 3 hours (plus 2 days) = 11:00 AM
<u>Converting to Denver time:</u>
- 11:00 AM - 2 hours = 9:00 AM
