Answer:
13 yds
Step-by-step explanation:
the blue side starter (B) swims 29yd in the time it takes the red side starter (R) to swim 21yd
their combined distance, when they meet, is 50yd (length of pool)
they pass each other and continue to the ends of the pool (combined distance, 100yd)
they swim towards each other again, and pass a second time (combined distance, 150yd)
at this point, R has swum 63yd (3*21) -- one length plus 13yd
so RS is 13yd from the blue end
Answer:
Step-by-step explanation:
The correct answer is D. If we are multiplying by 10 we would move the decimal place one place to the right to show that the number is now 10 times bigger. If we multiply by one hundred. We are getting 100 times bigger, so we would move the decimal place 2 places to the right.
The opposite is true if we are dividing. Instead of moving the decimal to the right to show that the number is getting bigger, we move to the left to show that the number is getting smaller. If we are getting smaller by 10, we would move the decimal one place to the left. In this case, we are getting 100 times smaller so we move the decimal two places to the left.
