Dr. Jagadish Chandra Bose used a crescograph to measure tiny increments in plant growth. If a plant stem grows at a uniform rate of $0.2\text{ mm}$ per hour, how much growth will the crescograph register over a period of $5\text{ hours}$?
$0.5\text{ mm}$
$1.0\text{ mm}$
$1.2\text{ mm}$
$2.0\text{ mm}$
Solution
Multiplying the growth rate by time gives $0.2\text{ mm/hour} \times 5\text{ hours} = 1.0\text{ mm}$.
