Question

A girl cycles for 3 hours at a speed of 40 km per hour. What distance did she travel?
​

Answer 1

Answer:

Distance= Time into speed

so distance= 40*3=120 km

Answer 2

$\red{ \large{ \bold{ \longrightarrow \:speed \: = \: \frac{distance}{time} }}}$

$\red{ \large{ \bold{ \longrightarrow \:distance = speed \times time }}}$

$\red{ \large{ \bold{ \therefore \:speed = 40 \: km/h }}} \\ \red{ \large{ \bold{ time= 3 \: hours }}}$

$\red{ \large{ \bold{ \longrightarrow \:distance = 40 \times 3 }}}$

$\red{ \huge{ \bold{ \Longrightarrow \:distance = 120 \: km }}}$
