Question

the circumference of four wheel of different car are 60 CM, 75cm, 90cm and 108cm they start moving simultaneously. what least distance should they cover so that each wheel make a complete number of revolution ​

Answer 1

Answer:

27metres is the least distance

after completion of..45,36,30,25 rotations..

Step-by-step explanation:

• the least distance which four vehicles cover...=The LCM of 60,75,90,and,108

• 2700cm is LCM
• 2700/100 m
• 27m
• after 27 metres travel each wheel rotates complete rotations...
• the rotations are as follows..

• (2700/60)=45
• (2700/75)=36
• (2700/90)=30
• (2700/108)=25

completes after travelling 27 metres...
