Question

what is the time when distance is 7150km and speed is 780km/h

Answer 1

Since,
v=d÷t
v=Velocity
d=distance
t=time.

Given:
v=780km/hr
d=7150km.

Note:If you want to convert it in S.I system you can but how I'm doing is also right.

Now,
v=d÷t
t=d÷v
t=7150÷780
=9.16hrs

Time is 9.16 hrs.

Hope this will help you.If possible please follow me.

Answer 2

GIVEN :
distance = 7150 km= 7150000m
speed = 780 km/hr
= 780000/3600
= 7800/36
= 1950/9 m/sec

Time = distance/speed
= (7150000/1950)×9
= 6435000/195
= 33000 sec
= 550 min
= 9 hr 10 min


hope this helped you.
