1. A race car driver pulls onto a circular track. After 10 seconds, his speed is 200 km/h. The car travels at a steady speed of 200 km/h for 100 seconds and then slows to a stop
in another 10 seconds. At what times, during that 120-second time period, did the car
change velocity? Explain your answer.

because they could drop even lower..

you already gave the answer

step-by-step explanation:

multiple all that

step-by-step explanation:

27×17

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
