1.	6. Travelling at a constant speed of 45 km/h, how longwill a motorcycle take to make 12 laps around arectangular track 800 m long and 400 m wide?
Answer» Speed of motorcycle = 45 km/h Length of Reactangular track = 800 m = .8 km Width of Reactangular track = 400 m = .4 km Perimeter of Reactangular track = 2(length + width) = 2(.8 +. 4) = 21.2 = 2.4 km Total distance covered= 122.4 = 28.8 km Time taken to cover a distance by motorcycle = Distance / speed= 28.8/45 = .64 hours = .64*60= 38.4 minutes thanks

Answer»

Speed of motorcycle = 45 km/h

Length of Reactangular track = 800 m = .8 km

Width of Reactangular track = 400 m = .4 km

Perimeter of Reactangular track = 2(length + width) = 2(.8 +. 4) = 2*1.2 = 2.4 km

Total distance covered= 12*2.4 = 28.8 km

Time taken to cover a distance by motorcycle = Distance / speed= 28.8/45 = .64 hours = .64*60= 38.4 minutes

thanks
