A car leaves a city at the rate of 60 mi/h and goes 80 miles before a second car follows at a rate of 70 mi/h. How long will it take for the second car to overtake the first?

practice. practice. practice.

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

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
