Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel.

astra-53 [7]

Answer:

Kevin=335.8years old

Step-by-step explanation:

K - D = 333

K - 2 = 400( D - 2 )

333 + D - 2 = 400D - 800

D - 400D = - 800 - 331

- 399D = - 1130

D = 2.8

K = 333 + 2.8

K = 335.8
