A "bullet" train set a new world record for train speed at 550 kilometers per hour during a manned test run on the test line in april 1999. the test line is 42.2 kilometers long. how many minutes would a test run on the test line last at this record-setting speed?

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
