Question

Ron walks 22.5m in 5s Find his speed

Answer 1

ɢɪᴠᴇɴ:

• Ron walks 22.5m in 5s

ᴛᴏ ꜰɪɴᴅ:

• Ron's speed

ꜰᴏʀᴍᴜʟᴀ:

$\tt\bf\purple{Speed = \frac{distance}{time}}$

ꜱᴏʟᴠɪɴɢ:

${\bf{Speed =\frac{22.5}{5} }}$

${\bf{➺ \: \frac{225}{10} \div 5}}$

${\bf{ ➺ \: = \frac{225}{10} \times \frac{1}{5} }}$

${\bf{➺ \: \frac{\cancel 225}{10} \times \frac{1}{\cancel 5} }}$

${\bf{➺ \: \frac{\cancel 45}{\cancel 10}}}$

${\bf{➺ \: \frac{9}{2}}}$

$\tt\bf\red{\frac{9}{2} = 4.5 \: metre \: per \: second}$

Answer 2

$here \: is \: your \: answer \: -$

☞$given \: - \: ron \: walks \: 22.5m \: in \: 5s. \\ \\ ☞to \: find \: - \: ron's \: speed. \\ \\ ☞proof \: - we \: know \: that \: \\ \\ ☞ speed \: = \frac{distance}{time} \\ \\☞ speed \: = \frac{22.5}{5} \\ \\ ☞ = \: \frac{225}{5 \times 10} \: \: (by \: removing \: point \: ) \\ \\ ☞ = \frac{45 }{10} \: \: \: ( \: by \: cutting \: 225 \: with \: 5 \: then \: we \: get \: 45) \\ \\ ☞ = \frac{9}{2} \: (by \: cutting \: 45 \: and \: 10 \: with \: 5 \: nd \: we \: get \: \frac{9}{2} ) \\ \\ ☞ = \: \frac{9}{2} = 4.5 \: metre \: per \: second.$

☞ $so \: our \: answer \: = \: 4.5 \: metre \: per \: second \:$
