Question

​A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from​ Earth, how long will it take the rocket to make the trip from Earth to the​ satellite? (Hint: Divide the distance to the satellite by the​ speed.) Write your answer in scientific notation.

Answer 1

Answer: Time taken =1.25 x 10^1 hours 0r  4.5 x 10^4s

Step-by-step explanation:

Step 1

how long will it take the rocket to make the trip from Earth to the​ satellite = Time taken for the rocket to make the trip from Earth to the​ satellite

Speed = Distance / Time ,

Time = Distance / speed

Step 2-- solving

Time = Distance / speed

Time=2.5×10^5 miles/2.0×10^4 miles per hour

=12.5 hours  = 1.25 x 10^1 hours

or 1.25 x 10^1 hours  x 3600 = 45,000 seconds = 4.5 x 10^4s
