ZARA AND JOHN ARE HIKING ON A TRAIL THAT IS 2 MILES LONG. THERE ARE SIGNS TO MARK EACH EIGHTH OF A MILE ALONG THE TRAIL

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'.

think about it deeply and passionately about this property

i am sorry
