By car, john traveled from city a to city b in 3 hours. at a rate that was 20 mph

higher than john’s, peter traveled the same distance in 2 hours. find the distance

between the two cities.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

40% off the regular price is the correct answer.
