Here is your answer hope it helps☺☺plz mark it as brainliest ☺
Diameter=60cm
Radius =60/2=30
No of revolution=140
Time taken for one revolution =1min
Distance covered =circumference of a circle=2*22/7*30=1320/7cm
Distance covered by 140revolutions=1320/7*140=26400cm
1m=100cm
1cm=1/100cm
1m=1/1000km
26400cm=264m=264/1000=0.264km
Distance covered in 1hour that is 60minute is=60*0.264=15.84km/hr
