The distance train a travels is represented by d=70t, where d is the distance in kilometers and t is the time in hours. the distance train b travels at various times is shown in the table. what is the unit rate of each train? which train is going faster

table

time (hours) distance(km)
2 150
4 300
5 375

Train B is going faster

Step-by-step explanation:

The distance Train A travels is represented by

where d is the distance in kilometers and t is the time in hours

The speed of train A is 70 kilometer per hour

To find speed of train B use the table

find out slope

The speed of train B is 75 km per hour

The speed of the train B is more

Train B is going faster

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

the answer is y = 11.54

hope this : )
