There's no set answer to that question, as it would depend on how fast you're going. And that would depend on quite a lot of things, how fit you are, how hard you're trying, what kind of bike you're riding, uphill/downhill, headwind/tailwind, if you're carrying any gear, if it's a sprint or a part of a longer ride, road/offroad....
Under most circumstances it'd probably take around 8 minutes, although a real pro under ideal conditions could pull it off in around 3 minutes on level ground. I could probably get it done in around 5 minutes.
There's virtually no way of telling, there are too many unknowns in terms of what road conditions they'll be riding on, what kinds of bikes they'll be using and how fit and old the family members are. I could probably do it in about an hour, if it's through an area with not too many hills or intersections. If the family has some riding experience you have a reasonable chance of pulling it off in 2 hours riding time, Count some break time in too.
6 kilometers per hours (18 divided by 3).
Answer: 10 km = 6.21371 miles
with average speed, 8-12 minutes approximately

hi if u want to increase the mileage in your bike you have ride the bike in 50km speed for first 2000 kilometer, and take a long distance drive like 50 to 70 maintain the speed limit only 50 or 55, for first 2000 km ride the bike your self don't give it to friends and others. gradually increase the speed after 2000km u ll get mileage up to 50 - 65
it would probobly depend on how fast you are going-if you are walking, in a car, on a bike, etc.......
Assuming "3 12" is meant to be 3 1/2 then it will be 28 km.
76 km/X h=16 km/1 h 76=16x 4.75 hours=x 4.75 hours is 4 hours and 45 minutes
63/20=3.15 hours in decimals 0.15*60=9 so 3 hours, 9 minutes at a steady pace of 20 km.
Depends on how hard you want to ride, and where you consider Scotland to start. By the road it's about 700 km between London and Edinburgh. A really fit rider would be able to cover that in two days riding if he's travelling light. Anyone who can take 4-6 hours in the saddle daily should be able to do it in seven days, even when carrying gear. For someone with a bit of experience in bike touring I reckon 4-5 days would be a nice target.
