Step-by-step explanation:
What is 8 meters increased by 28%?
Well, first, you need to convert 28% to a decimal by moving the decimal two to the left by dividing by 100
28÷100=.28
or
28%⇒28⇒.28
Then you multiply
8 meters times .28
Then you add 2.24 to 8m (since its the original number)
Your answer is 10.24m
You need to find the total distance and the total time. The total distance is two times the distance to school, 2d.s=d/t=>t=d/sWhere s is speed, d is distance and t is time. So the time taken to get to school is:d/s1and the time taken to get back is:d/s2so the total time is:d/s1+d/s2=d(1/s1+1/s2)So, as speed = distance/time, divide the total distance by the total time:2d/d(1/s1+1/s2)=2/(1/s1+1/s2)=2/(1/20+1/40)=80/3≈26.7km/hr
