Question

Tyres of the cycle have diameter d metre. It is moving at a speed 15 m/s. Tyres of the cycle revolves completely 120 times in 2 minutes. Find the total distance travelled by the circle in this 2 minutes, also find the value of diameter d.​

Answer 1

Step-by-step explanation:

Distance = Speed x Time

Distance = 15 x 120 sec ( convert min into sec)

Distance = 1800 m

Diameter = Distance

No. of revolutions

Diameter = 1800/120

= 150 m

Distance = 1800 m

Diameter = 150 m
