Question

A factory makes 6.3 biscuits every second . How many biscuits will they make in 1 minute?

Answer 1

$$\begin{gathered} \mathrm{Number}\mathrm{of}\mathrm{biscuits}\mathrm{the}\mathrm{factory}\mathrm{makes}\mathrm{every}\mathrm{second}=6.3 \\ \mathrm{As}\mathrm{there}\mathrm{are}60\mathrm{seconds}\mathrm{in}1\mathrm{minute}. \\ \mathrm{Therefore},\mathrm{the}\mathrm{number}\mathrm{of}\mathrm{biscuits}\mathrm{makes}\mathrm{in}1\mathrm{minute} \\ =\mathrm{number}\mathrm{of}\mathrm{biscuits}\mathrm{the}\mathrm{factory}\mathrm{makes}\mathrm{in}60\mathrm{seconds} \\ =60\times \left(\mathrm{number}\mathrm{of}\mathrm{biscuits}\mathrm{factory}\mathrm{makes}\mathrm{in}1\mathrm{second}\right) \\ =60\times 6.3=378. \\ \mathrm{Hence},\mathrm{the}\mathrm{factory}\mathrm{makes}378\mathrm{biscuits}\mathrm{in}1\mathrm{minute}. \end{gathered}$$
