Answer:
30 and 33 years
Step-by-step explanation:
Let Lara be x years
Cam =x+3
x+x+3=63
2x+3=63
2x=63-3
2x=60
x=60/2
x=30
Lara=30years and Cam =30+3+33years
Hi. Good?
To solve is to use the formula:
D = v.t
14 = v. 15
v= 14/15
v = 0,9333..mpm
15m = 900s
14 = v. 900
v=14/900
v=0,01555...mps
I put the result in miles per minute and miles per second.
Thanks, I hope I have helped.
