Question

the circumference of the front wheel of a car is 10 decameter and that of the hand will in 16 dm how many Revolution more will the first will take then the second is covering a distance of 96 km ​

Answer 1

Answer:5.76

Step-by-step explanation:

2×pi×r× not revolution of smaller wheel=2×pi×R× no of revolution of larger wheel

r/R=8/5

Now,

10dm×0.01 = 0.1 km

0.1×r=96

r=9.6

R= 9.6×5/8

=15.36

Difference = 15.36-9.6

=5.76
