glorias car is traveling 20 miles per hour slower than twice the speed of noah's car. she covers 120 miles in 2.5 hours. how fast is noah driving

Answer 1

g = 2n -20

120 = 2.5g = 2.5(2n-20) = 5n -50

120 = 5n-50

24 = n-10

n=24+10 = 34

34 mph = Noah's speed

g = 2(34)-20 =68-20= 48 mph= gloria's speed. gloria beats Noah, winning the glory gloriously

except when she competes against Noah's ark in the ocean. then she Loses big time

d =rt

120 = 2.5g

g = 120/2.5 = 1200/25 = 48

48=2(34)-20 = 68-20=48
