Lets use proportion
let the perimeter of the smaller figure be 'x'
8:18::x:24
Product of means=product of extreames
24 x 8= 18 x 'x'
192=18x
x=10.6666667 units
Ans: the perimeter of the smaller figure is 10.6666667 units
Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
