Aturtle walking at an average speed of 3/10 mile per hour takes 13/20 hour to walk from its home to the seashore. how long will the journey take if the turtle doubles its average speed?

13/40 because when you double the average speed it would be 3/10*2/1=6/10. Since you double the speed, it will take less time to travel, so you do 13/20*1/2=13/40. The greater the average speed, the less time it takes to travel.

child does not get an education so she can use the molla on junk

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
