Question

a scooterist covers 48 km in 1 hour and a car driver covers 120 km in 2 hours find the ratio of their speed ​

Answer 1

$speed = \frac{distance}{time} \\Hence, speed\: of\: scooterist\: is\\S_{1} = \frac{48}{1} \\= 48 km/h \\Speed\:of\: car \\\\S _{2} = \frac{120}{2} \\= 60\: km/h\\Hence, the\: ratio\: of\: thier\: speed\: is \\\\48:60\: = 4:5$
