The amount of time it takes you to cycle 20 miles depends on your health, the type of bike you have, the route you're riding and the environmental conditions. Google Maps will easily tell you that – in my area – to travel 20 miles by bicycle will take you 1 hour and 48 minutes. You shouldn't really count on that ETA.

The car travels 20 km in 20 minutes so it travels 20 km*60 min/20 min = 60 km. It travels 60 km in 60 mins or 1 hour, so its speed = 60 km/h.

The faster you make your bike go, the more calories you burn. A light ride of 10 to 11.9 mph burns 844 calories for a 155-pound person. Go at a vigorous 14- to 15.9-mph pace and burn 1,408 calories. When you are racing at paces of 16 to 19 mph, expect to sizzle 1,688 calories in two hours.

The average person can cycle between 15 and 20 miles in 1 hour; however, it depends on the type of bike, terrain, weather and intensity of the rider. Over the ten rides, I would cycle 5km (3.1mile) every 10 minutes on average, which would give me 30km (18.6mile) over the hour.

Subra Velu, 4-10 hours per week of walking / cycling. If you can do 40KM everyday, I envy on you. 40KM a day is the right amount of distance you can exercise everyday or even every alternate day. For a beginner to inexperienced professional, 40KM will take 2 hours of riding.

I think you may mean a 60kg person walking at medium speed for 20km. You will 'burn' approximately 300 calories (circa 1,300 kJ) an hour at say 3 to 4 mph (5 to 6.5 kph). So at a nice moderate stroll (3mph/5kph) you'll take four hours = circa 1,000 to 1,200 calories/5,000kJ.

Roughly 20 pounds, or 9 kilograms. The cheaper the road bike, the heavier it will be. On the lowest of the low end (<$500), a bike that's over 25 lbs is heavy, but most of them fall pretty close to that. Mid-range bikes ($500–1200) should be under 21 lbs.

If you are riding 20 km/h average on your bike (without a break), you can even finish it in 2,5 hours. The normal speed of a bicyclist is about 10 km/h and say you and your friends take a break in the meantime, you and your guys arrive the destination in about 6 hours, still less than 8 hours.

A 5 kilometre cycle is something of a benchmark for cyclists - for elite riders, it's a high octane sprint to the finish, whilst for less experienced riders, it's a twenty minute slog of the mind and body.
