Answer / ajeet
Let the revolutins made by bigger wheel is: x
then revolution by smaller wheel will be: x+10
Now, the distance covered by both wheels will be same.
So,
7(x+10)=9x
7x+70=9x
70=2x
35=x
so distance travelled=9*35=315
or 7*45=315

Answer / suryaveer
Let the revolutins made by rear wheel be: x
then revolution by front wheel will be: x+10
Now, the distance covered by both will be same.
So,
7(x+10)=9x
7x+70=9x
70=2x
35=x
So the total distance is 7*35 i.e. 315 feets.

Answer / srikar
315feets we assume x be the of revolutions made my x but
revolutions made by fornt wheel is x+10 assume distance
travelld by both wheels is equal then
7(x+10)=9x => x=35
distnce =45*7=315

Answer / karthikeyan
Revolutions of front wheel=10
then the revolutions of back wheel is same as front wheel.
But actual distance covered by both of them is
Let as assume distance covered by wheel is x
x=((10*7)/2)*7=245 feets.
