Question

An Aeroplane travelled 2781.20 km in 6 hours. Find the average speed of the aeroplane in km/hr.

Answer 1

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.
