we need to travel 200km at 55 km per hour so that's 200 divided by 55 = 3.636 hours
An electrical signal in a copper wire moves roughly at 2/3 the speed of light in a vacuum, so, about 200,000 km/second. Since the Earth has a circumference of about 40,000 km, that means such a signal can go all around the Earth in 1/5 of a second.
Radar waves travel at the speed of light, approximately 300,000 km/second, so it would take 1/30,000 second for them to make the 10 km round trip.
They use a ski-lift. The ski-lift pulls them up-hill - against the force of gravity until they reach the top of the run. They then ski back down the slope.
A ski-doo goes 50-60 km.
