Step-by-step explanation:
Convert all to decimals
percent means parts out of 100
13%=13/100=0.13
'of' means mutiply
Tom=13% of 4
tom=0.13 times 4
tom=0.52 lb
Lisa=0.6 lb
Jane=0.12 of 4
jane=0.12 times 2
jane=0.48
Tom=0.52
Lisa=0.60
Jane=0.48
Lisa used the most

gain means you’re getting more, which is positive

Answer:
Option A - The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Step-by-step explanation:
Given : The distance Train A traveled is modeled by the function 
where d represents distance in miles and t represents time in hours.
To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?
Solution :
Distance traveled by Train A in 1 hour is


Distance traveled by Train B in 1 hour is


or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour
Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Hence, Option A is correct.
