Question

In aeroplane is flying at a speed of 625 km/h.
a. If the distance between two cities is 1250 km, find the time taken to reach the
destination by the aeroplane.
b.How much distance is covered in 45 minutes?
c. How much distance is covered in 15 seconds?
​

Answer 1

Answer:

a) 625 km= 1 hr

625x2 = 1250 km

time taken for 1250 km = 1x2

                                      = 2 hrs

b) 1 hr = 60 mins

60 mins= 625 km

1 min = 625/60 km

45 mins = 625/60 x 45

              = 468.75 km

c) 625 km = 625000 m

1 hr = 60 min

60 min =3600 sec

3600 sec = 625000 m (made in one unit, so like its metre per second)

1 sec = 625000/3600

         = 6250/36

15 sec = 6250/36 x 15

          = 2604.1 m (approximate)

          = 2.6041 km
