1.	6. Travelling at a constant speed of 45 km/h, how long!will a motorcycle take to make 12 laps around arectangular track 800 m long and 400 m wide?
Answer» Given:Speed=45km/heNo of laps=12length =800mwidth=400m Here total distance of track = 2(800+400)=2400 m Total distance he has to travel = 12*2400=28800 m = 28.8 kmSince he takes 12 laps around Therefore time taken =Distance/speed= 28.8/45=0.6 hours (apprx)

Answer»

Given:Speed=45km/heNo of laps=12length =800mwidth=400m

Here total distance of track = 2(800+400)=2400 m

Total distance he has to travel = 12*2400=28800 m = 28.8 kmSince he takes 12 laps around

Therefore time taken =Distance/speed= 28.8/45=0.6 hours (apprx)
