Answer 1

${\pink{hola!!}}$

Given:-

Diameter (D)=88cm

Radius (R)=88/2

Number of revolution=60 km/circumference of the wheel

60 km in meters =60000 meters
60000 in centimeters=6000000 cm

Circumference =2πr
=2×22/7×88/2
=22/7×88
=1936/7
=276.5cm

Revolutions=6000000/276.5
${\green{Revolutions = 21699.8}}$
