Radius of the wheel = 63/2 cm
=====================
Distance covered in one revolution = Circumference of the circular wheel
= 2πr
= 2×(22/7)×(63/2)
= 198 cm
-------------------------------
Speed = Distance/Time
= 130 rev/min
= 130×198 cm/min
= 25740 cm/min
= [25740×(1/1000)]÷(1/60) km/hr
= 1544.4 km/hr

Diameter = 63 cm
Radius = 63/2 cm
Circumference = 2πr = 2 x 22/7 x 63/2
= 198 cm
Per minute = 130 revolutions
198 x 130 = 25740 cm
Speed = 25740 cm/min
Radius = 63/2 cm
Circumference = 2πr = 2 x 22/7 x 63/2
= 198 cm
Per minute = 130 revolutions
198 x 130 = 25740 cm
Speed = 25740 cm/min
DEAR I DIDN'T MARK YOUR ANSWER AS THE BRAINLIEST BECAUSE THE CONVERSION OF SPEED WAS NOT DONE.
BUT THANKS A LOT FOR ANSWERING MY QUESTION
