25/3%
After how many
years would she earn 750 as simple
interest?​

Answer 1

Step-by-step explanation:

Radius of the circular orbit of along which the

satellite is moving = 42250 km.

Time taken by the satellite to complete one

revolution around earth = 24h.

Distance travelled

We knowthat speed =

Time taken

Distance travelled by the satellite in one revolution around earth = 2X TXr

where r is the radius of the orbit

Distance travelled = 2xTX 42250

2xx42250

= 265571.43 km

Time taken = 24 hr

Therefore speed 265571.43 km = 11065.47 km/hr

24 hr

The speed of the satellite = 11065.47 km/hr
