Question

A robot is programmed to move along a straight-line path through two points 𝐴 and 𝐵. It travels at a uniform speed that allows it to make the trip from 𝐴(0,−1) to 𝐵(1, 1) in 1 minute. Find the robot’s location, 𝑃, for each time 𝑡 in minutes.

1. t = 14
2. t = 0.7

Answer 1

it moves the sqr5 in 1 minute

in 14 minutes it moves 14sqr5

in .7 = 7/10 part of a minute it moves .7sqr5

for 1 minute

d^2 = (0+1)^2 + (-1-1)^2 = 1 +4 = 5

d = sqr5
