Answer: - n/35+n/45=2.5 or just 49.22
Step-by-step explanation:
use the formulas t total=t1+t2 and V=n/t
n=distance, V=speed, and t=time
35=n/t1, and t1=n/35
her train ride follows the same path at 45mph
45=n/t2, and t2=n/45, so then you get - n/35+n/45=2.5

Step-by-step explanation:
First fraction:
Numerator:
(17/40 + 0.6 - 0.005) = 1.02
1⅕ = 1.2
(1.2 ÷ 1.02)×1.7 = 2
Denominator:
5/6 + 4/3 - 53/30
Lcm: 30
(5×5 + 4×10 - 53)/30
12/30 = 0.4
Fraction value: 2/0.4 = 5
Second fraction:
4.75 + 7.5 = 12.25
33 ÷ 33/7
33 × 7/33 = 7
12.25/7 = 1.75
1.75 ÷ 0.25 = 7
Final answer:
5 + 7 = 12
