Question

An aeroplane is flying at a speed of 720 km/h.
1. If the aerial distance between two cities is 1800 km, how much time will the aeroplane take in crossing these cities?
2. How much distance does the aeroplane cover in 40 minutes?
3. How far will it fly in 15 second?

Answer 1

Speed of airplane=720km/hr
1)Distance =1800km
Time =Distance/Speed
=1800/720
=2.5hr
2)Time =40min
=40/60 hr
=2/3 hr
Speed =720km/hr
Distance=Speed×Time
=720×2/3 km
=480km
3)Time =15sec
=15/3600 hr
=1/240 hr
Speed=720km
Distance=Speed ×Time
=720×1/240 km
=3km

Answer 2

Answer:

2.5, 480 km and 3km
