\huge\sf{Question}
A bucket is raised from a well by means of a rope which is wound round a wheel of diameter 77 cm. Given that the bucket ascends in 1 minute 28 seconds with a uniform speed of 1.1 m/sec, calculate the number of complete revolutions the wheel makes in raising the bucket.

Hello Finex!

  \huge  \dag\sf \blue{answer}

Time of ascent=1 minute 28 seconds

=60+28=88 seconds

Distance moved by bucket=speed×time

 = 1.1 \times 88m \\  \\  = 96.8m

Circumference of wheel

 = 2\pi r

 = 2 \times  \frac{  \cancel{22}  \:  \: ^{11} }{ \cancel7} \times   \frac{ \cancel{ {77}} \:  \: ^{11} }{ \cancel2}  \\  \\  = 2 \times 11 \times 11 \\   \\  = 22 \times 11 \\  \\  = 242cm \\  \\  = 2.42m

Number of complete revolutions the wheel makes while rising bucket

 =  \red{ \frac{96.8}{2.42}} \\  \\   \boxed{ \sf \green{ = 40}}
