Answer: total comes to 4X - 12Y + 4
Step-by-step explanation:
20.6 divided by 9.7 is 2.12371134
T1 + t2 = 2h and 30min;
t1 * 600 = t2 * 400 => t2 = (3/2) * t1;
then, t1 + (3/2) * t1 = 2h and 30min => 2t1 + 3t1 = 5h => 5*t1 = 5h => t1 = 1h => t2 = 1h and 30 min;
The distance is 2 * 1 * 600 = 1200miles;
I do know the bottom one is 2.8
Top is 1.6
I don’t know the middle one
