We have:
20-minute bike ride
It takes 4 minutes for him to go a kilometer
k is the number of kilometers Garret has already biked
Number of minutes Garret has already biked:
4k
Number of minutes remaining in Garret's ride
20-4k
4(5-k)
Number of kilometers Garret has left to ride
5-k
Answer:
No, doubling the base and height would actually quadruple the area,
Step-by-step explanation:
With the original measurements of b = 3 ft and h = 5 ft,
<em>b x h = A</em>
<em>(3) x (5) = </em><em>15 ft</em>
So lets say we <em>doubled</em> the factors:
<em>(2)(3) x (2)(5) = A</em>
We would end up with 60 feet, four times that of 15.
<em>(6) x (10) = </em><em>60 ft</em>
