Multiply this 15 mph by the conversion factor derived from 1.6 km = 1 mi:
15 mph 1.6 km
------------ * ---------- = 24 km/hr
1 1 mi
The cyclist's speed in km/hr is 24 km/hr.
In 3 hrs the cyclist can cover (24 km/hr)(3 hr) = 72 km.
To answer this question, you need to translate the description into a formula. The formula that can be made should be: length of rectangle= 3+ (4* rectangle width). You already know the length, so you can find the width by inserting it to the formula. The calculation would be:
Length= 3+ 4*width
27ft= 3ft+ 4*width
4*width= 27ft-3ft= 24ft
width= 6ft
I believe it’s b but I’m not super sure
