1. 22 cm
2. 4 times
3. (y÷4)² which is y²÷ 16
4. 3 X side, or side+side+side
5. I don't understand.
6. For 2 hours, dist=60 km.
    For the 3 hours, dist= 105 km. 
    Total Dist.=165 km. Total time= 5 hours. So, avg speed= 165/5= 33 kmph
7. 65, because if there was a remainder of 65, then you will simply divide it by one and leave a remainder of 0.
