Answer:
15 hours
Step-by-step explanation:
Speed is defined as the distance moved per unit time hence s=d/t and making t the subject of the formula then t=d/s where t is time taken, d is distance covered and s is the speed.
Substituting 15000 miles for d and 1000 mph for s then
T=15000/1000=15 hours
Therefore, maintaining the same speed, it will take 15 hours to get to mars
