Answer:

35.595

Step-by-step explanation:

Diameter of wheel = 90cm.

Radius of the wheel = 22/7 * 90 = 282.5 cm

Each time, the wheel makes a revolution, it cover 282.5cm.

Revolutions in one minute = 210

Distance covered in 1 minute = 59,325 cm or 593.25 m

Distance covered in 60 minutes = 35595 m           [593.25*6]

Speed of bus = 35.595 km/hr
