Question

How do we solve this?

Answer 1

Answer:

36 seconds

Step-by-step explanation:

Diameter (d) = 28 m

Radius (r) = d/2 = 28/2 = 14 m

Radius (r) = 14m = 14/1000 km = 0.014 km

Circumference = 2 × pi × radius

Circumference = 2 × (22/7) × 0.014

Circumference = 2 × 22 × 0.002

Circumference = 0.088 km

Time = Distance/ Speed

Here, Distance = Circumference

So,

Time = Circumference/ Speed

Time = 0.088 / 8.8

Time = 0.01 hour

Time = 0.01 × 60 = 0.6 minutes

Time = 0.06 × 60 = 36 seconds
