pls help me
A space craft travels 3.45 x10 8 km in 5 x 10-3 hours . Find its speed.
Answers
Answer:
the speed of the spacecraft is 0.69*10 11km/hr
Step-by-step explanation:
speed=distance/time
distance is 3.45*10 8km
time is 5*10 3
s=3.45*10 8/5*10 -3
=0.69*10 11km/hr
Concept: Speed tells U.S. how briskly one thing or somebody is motion. You'll notice the common speed of AN object if you recognize the space traveled and also the time it took. The formula for speed is speed = distance is divided by time.
Given: Distance traveled by the spacecraft is 3.45×10^8 km
Time taken by the spacecraft is 5×10^-3 hr.
Find: Calculate the speed of the space craft.
Solution: Speed= Distance/ Time
Distance traveled by the spacecraft is 3.45×10^8 km
Time taken by the spacecraft is 5×10^-3 hr.
Speed= 3.45×10^8/ 5×10^-3
= 0.69×10^8+3
= 0.69×10^11
= 6.9×10^10
Final answer: Speed of the space craft is 6.9×10^10 km/hr.
