I believe A=2 and B=6, sorry if I’m wrong
Solve for m:
2 m - 5 - 3 = 10 - m
Subtract like terms. -3 - 5 = -8:
2 m - 8 = 10 - m
Add m to both sides:
2 m + m - 8 = (m - m) + 10
m - m = 0:
2 m + m - 8 = 10
2 m + m = 3 m:
3 m - 8 = 10
Add 8 to both sides:
3 m + (8 - 8) = 8 + 10
8 - 8 = 0:
3 m = 10 + 8
10 + 8 = 18:
3 m = 18
Divide both sides of 3 m = 18 by 3:
(3 m)/3 = 18/3
3/3 = 1:
m = 18/3
The gcd of 18 and 3 is 3, so 18/3 = (3×6)/(3×1) = 3/3×6 = 6:
Answer: m = 6
We first find out time taken to travel for just 1 km
2hrs is equivalent to 120 minutes
120 km = 120 min
1 km = x (where x is the time taken to travel 1 km).
we simplify the equation by cross - multiplying the equation , so:
120 × x = 1 × 120 → 120x = 120 → x = 120/120 → x = 1
So the car covers 1km in 1 minute
For 300 km the car will take 300 × 1 minute = 300 minutes
we convert minutes to hours by dividing by 60 → 300 / 60 = 5
Therefore the car will take 5 hours to cover 300 km.
