Answer:
x=3
Step-by-step explanation:
The girl's speed is 1380mm/sec * 1cm/10mm * 60sec/minute (since 1cm=10mm and 60 sec=1 minute)= 1380*60cm/10min= 1380*6cm/min
=8280 cm/min. For the turtle, we have 1584 m/hr * 1 hr / 60 min * 100 cm /1m (we have to make sure that they cross out, so e.g. for the hour we multiply it by 1 hr/60 min since the original hour is on the bottom)= 158,400cm/60min
=15840cm/6min
= 2640 cm/min
Since the girl is 8280 cm/min and the turtle is 2640 cm/min, we divide them to get 8280/2640= around 3.136 cm/min
Hello there!
Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.
Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25
So if:
48 feet ......> 12 inches
x feet ........> 0.25 inches
Cross multiply
12 * x = 0.25 * 48
12x = 12
Divide both sides by 12
12x/12 = 12/12
x = 1
The correct answer is option D, 1 foot
I hope this helps! Please let me know if you have any question.
