Answer 1

Step-by-step explanation:

SPEED= DISTANCE/TIME

TIME= SPEED/DISTANCE

DISTANCE= TIME/SPEED

Answer 2

Answer:

abc are collinear

Step-by-step explanation:

A(1,−1),B(5,2),C(9,5)

AB=(5−1)2+(2−(−1))2=42+32=25=5

BC=(9−5)2+(5−2)2=42+32=25=5

CA=(9−1)2+(5−(−1)2)=82+62=100=10

∴ as AB+BC=CA

A,B,C are collinear. please mark me as brainlist for this and
