Question

A cart is running at an average speed of $3.6km/hr$. How much time will it take to go $380$ metres?

Answer 1

Average speed of cart $s=3.6$ km/hr

$s=3600$ meter/hr

$=\frac{3600}{60}$ meter/min

$=60$ meter/min

Distance traveled $d=380$ meters

Time $t=?$

Now, $speed=\frac{distance}{time}$

$s=\frac{d}{t}$

$60=\frac{380}{t}$

$t=\frac{380}{60}$

$t=6\frac{1}{3}$ min

$t=6$ min $20$ sec
