A car is traveling at a speed of 120 kilometers per hour. What is the car's speed in miles per hour? How many miles will the car travel in 4 hours?

The car's speed is 74.5444 mi/hr. It travels 298.2576 miles in 4 hours.

Step-by-step explanation:

If we want to know the speed in mi/hr, we must convert the km to mi. We can convert from kilometers to miles as follows.

mi = km * 0.62137

Then, if the car is moving at 120 km / hr, we have that the car is moving at

120*0.62137 mi /hr, which is 74.5644 mi/hr. If we want to know how many miles the car travels in four hours, we multiply the speed times the total time. Hence

total distance = 74.5444 mi/hr * 4 hr = 298.2576 miles.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
