The distance between A and B is 19 km. A cyclist starts from A at a constant speed towards B. A car leaves from A 15 min later in the same direction. In 10 min it catches up with the cyclist and continues towards B; after reaching B, it turns around and in 50 min after leaving, car encounters the cyclist the second time.
The speed of the cycle is
find the remainders:
a) (37^288)/100
b) (12^107)/37
Amit covers a certain distance with his own speed, but when he reduces his speed by 10 KM/hr his time duration for the journey increases by 40 hours, while if he increases his speed by 5 km/hr from his original speed he takes 10 hours less than the original time taken. Find distance covered?
