Rachel and Roshal started their journey by bike at 10 am from the same place. They are traveling at speeds of 30 km/hr and 35 km/hr respectively. How far apart will they be at 1:15 pm?

13.25 km apart

Step-by-step explanation:

30 km/hr: 97.5km

35 km/hr: 113.75

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'.
