3B + 3C = 24 (so B + C = 8)
4B - 4C = 16 (so B - C = 4)
Now we can use:
B + C = 8
B - C = 4
Add the equations:
2B = 12
Boat = 6
Subtract the equations:
2C = 4
Current = 2
Check:
With the current, the boat moves down the river at (6+2)=8 mph, or 24 m in 3 h.
Against the current, it moves up the river at (6-2)=4 mph, or 16 m in 4 h.
it was going from buglers bay to duck wharf and the current was against it canoe b took 5 hours to make the trip, wat was the rate of the current?8
No, you cannot travel internationally with an expired passport. You must renew your passport before traveling.
It hasn't ended. People are still traveling by train today.
35 mph
35 mph
8
Since the distance downstream (with the current) equals the distance upstream (against the current), and if we: Let B stand for the speed (rate in mph) of the boat in still water, and using the formula rate X time = distance, the equation will be: (B+7) x 3 = (B-7) x 5 3B + 21 = 5B - 35 56 = 2B B = 28 mph Traveling downstream, the current will cause the boat to go faster so the 7 mph current is added to the boat's still water speed. Traveling upsteam the current slows or decreases the boat's rate so the current's speed is subtracted from the boat's still water speed.
Traveling 600 million light years would take an impossibly long time, considering the current limits of our technology. Even traveling at the speed of light (which is not feasible for matter with mass), it would still take 600 million years to cover that distance. The vastness of space makes interstellar travel on such a scale unrealistic with our current knowledge and technology.
No. The bullet will actually travel much slower due to wind resistance.
Yes, you can still use your passport with your maiden name for travel purposes as long as it is still valid. However, it is recommended to update your passport with your current legal name to avoid any potential issues during travel.
With current technology, it is not possible to even come anywhere close to the speed of light. For example, traveling at 1/10 the speed of light is still science fiction. On the other hand, for anything that does NOT travel at the speed of light, it is impossible to actually attain the speed of light. In theory you might get close. There are some particles, such as photons and the hypothetical gravitons, which ONLY travel at the speed of light.
If you are worried about medical expenses or trip cancellation, then single trip travel insurance might be a good idea. Still, it is relatively rare to get this kind of insurance for intra-country travel.
