Sorry; needed some correction
The front wheels of a wagon are 2p feet in circumference and the back wheels are 3p feet in circumference. When the front wheel have made 10 more revolutions than the back wheels how many feet has the wagon traveled.
Please explain your answer. thanks
2p*(n+10) = 3p*n
=> n = 20
distance travelled = 2p*(n+10) = 60p i.e. E
