A bakery and a library are 120 m apart.
They are located between Hong's house and Jeya's house.
The bakery is exactly half-way in between the two houses while the library is closer to Jeya's house.
One day, Hong and Jeya started cycling from their houses at the same time and they arrived at the library together.
Jeya cycled at 70 m/min while Hong cycled at a speed of 15 m/min faster than Jeya.
a) how much further did Hong cycle than Jeya?
b) how far is Jeya's house than the library?
