On the real number line below, with coordinates as labeled, an object moves according to the following set of instructions: From point P the object moves right to , then left to R, then right to S, and finally left until it returns to its original position at P. Which is the closest estimate of the total length, in coordinate units, of the movements this object makes?

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'.

it’s supposed to be -4+45=41
