Question
marys pace maesures 35 cm. If she walks 2,000 paces, how many meters did she walk
Hi Lexie
This problem is about multiplication and unit conversion. We should first of all convert centimeter to meter, since this is what the question asks for in the end.
Recall that 100 cm = 1 m. Dividing both sides by 100, we get 1 cm = 1/100 m. Accordingly, 35 cm = 35/100 m. We can write this fraction "35/100" as 0.35 meter.
If one pace measures 0.35 m, then 2000 paces would cover 2000 x 0.35 m. So, the answer is 700 meters.
