Detailed Solution
Download Solution PDFप्रयुक्त अवधारणा:
वृत्त की परिधि = 2 × π × r
गणना:
पहिये की परिधि = 2 × 22/7 × 182 = 1144 सेमी
यहाँ, ठेले 60 मिनट में 66 किमी चल सकता है, तो ठेला 1 मिनट में तय कर सकता है = 66/60 = 1.1 किमी = 110000 सेमी
अब ठेले का पहिया प्रति मिनट चक्कर लगाता है, 110000/1144 = 96.15 ~ 96
∴ सही उत्तर 96 है।
