A barge moves 13 km/h in still water. It travels 25 km upriver and 25 km downriver in a total of 26 hr. What is the speed of the current?

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

b. f(x) = –√x + 3this is the correct answer
