6 teams 5 times the key word is times this means multiply so 6x5=30
Multiply everything by 180 first, to cancel out fractions if you want.
so, 120x - 45 = -36x +20
then, solve, 156x = 65
x = 65/156
simplify to x = 5/12
Answer:
120 km
distance = speed * time
90 minutes can be converted to 1.5 hours
speed given 80 km/h and time given 1.5 hours
so distance = 80 * 1.5 = 120 km
