Answer:
67
Step-by-step explanation:
The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 4.795 cm/minute
<em><u>Solution:</u></em>
Given that,
Total distance = 189 cm
They crawl towards each other at rates that differ by 1 cm a minute
Let the speed of snail 1 be "x"
Let the speed of snail 2 be "x + 1"
Total time = 22 minutes
Since the snails are moving towards each other,
Speed = x + x + 1 = 2x + 1
<em><u>How fast is each snail crawling?</u></em>

Thus,
Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 3.795 + 1 = 4.795 cm/minute
