प्रश्न
An Aeroplane travelled 2781.20 km in 6 hours. Find the average speed of the aeroplane in km/hr.
उत्तर
In 6 hours the distance travelled = 2781.20 km
In 1 hour the distance travelled = `2781.20/6` km
= `((278120/100))/((6/1))`
= `278120/100 xx 1/6`
= `278120/6 xx 1/100`
= `46353 xx 1/100`
= 463.53 km
Average speed of the aeroplane = 463.53 km/hr.
