Question

An aeroplane covers 1485 kilometres in 1 hour how much distance will it cover in 72 hours

Answer 1

1hr.=1485 km

72hrs.=1485×72

=1,06,920km

hope it helps

Answer 2

Answer:

distance = 106920 km

Solution:

Data:

Distance = d = 1485 kilometer = 1485 km

Time = t = 72 hours = 1 hr

Required:

Distance when time is 72 hours = ?

Calculation:

we know that

velocity = v = distance / time = d / t

putting values we get

v = 1485 / 1 =  1485 km/hr

Now when time = t = 72 hr then

Again using formula

      v = d / t

⇒  d = v × t

putting values we get

     d = (1485 × 72) km

     d = (1485 × 72) km

    d = 106920 km

So

the airplane covers 106920 km in 72 hr
