Question

Running along a rectangular track 50m × 40 m you complete one lap in 100 s. What is your average velocity for the lap ?

Answer 1

Answer:

1.8 m/s

Explanation:

Distance = 2*50 +2*40 [m] = 180 [m]

Time = 100 [s]

Velocity = Distance/Time = 1.8 m/s

Answer 2

Average velocity for the lap is 1.8 m/s

GIven:

Length of rectangular track = 50 m

Width of rectangular track = 40 m

Time taken to cover a lap = 100 seconds

Find:

Average velocity for the lap

Computation:

Perimeter of rectangle = Length of one lap

So,

Perimeter of rectangle = 2(l + b)

So,

Length of one lap = 2[50 + 40]

Length of one lap = 2[90]

Length of one lap = 180 meter

Average velocity = Distance / Time

Average velocity for the lap = 180 / 100

Average velocity for the lap = 1.8 m/s
