Rosa is filling up the back of her dump truck with cedar mulch for a delivery to a landscaped shopping center. the mulch is being pumped into the truck. after 30 minutes, the truck is 75% full and weighs 33 tons. fifteen minutes later, rosa's truck is fully loaded and weighs 42 tons. if rosa's truck weighs 15 tons when it is empty, what was the rate in tons per minute that the mulch pump took to load the truck?
a. 0.6 tons per minute
b. 0.93 tons per minute
c. 1.07 tons per minute
d. 1.67 tons per minute

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
