The driving distance between Denver and Chicago along Interstate 80 is
about 1020 miles. About how long
would it take to drive that distance
at 60 miles per hour?

17 hours.

Step-by-step explanation:

Formula

d = r * t

Givens

t = ?

d = 1020 miles

r = 60 miles per hour

Solution

1020 = 60 * t             Divide by 60

1020/60 = t

17 hours.

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
