Question

9. A wheel of circumference 2.8 m revolves 765 times in traversing a certain distance. How many revolutions
does a wheel of circumference 1.7 m make in traversing the same distance.
​

Answer 1

Step-by-step explanation:

1. distance= 2.8×765=2142m
2. then, no. of revolution = 2142/1.7=1260times

Answer 2

Answer:

circumference=2.8m

No. of revolutions=765

Distance travelled=2142m

circumference of second wheel=1.7m

distance=2142m

let the no of revolutions be x

X *1.7=2142

therefore x = 2142/1.7=1260 (Answer)
