8. Alana rides a bike 20 miles in 1 1/2 hours. How far can she go in 2 hours?

Step-by-step explanation:

Calculate the rate Alana can ride in an 1.5 hours

rate = speed = distance / time

speed is 20 miles / 1.5 hr

speed = 13.333 miles/hr   mph = miles per hour

Can you now figure out how far Alana can ride in 2 hours?

disatnce = speed (miles/ hr)  x time (hr)    speed = 13.333 mph and time = 2 hrs

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
