Space Explorer B travels ? miles per hour faster/slower than Space Explorer A.​

Answer 1

Answer:

1,600;

faster

Step-by-step explanation:

Distance in miles travelled by Space Explorer B is given as y = 8600x, where,

y = distance travelled

x = hours of flight

Distance travelled By Space B in 1 hour:

y = 8600(1) = 8600 miles

Speed (miles per hour) = distance travelled over time = 8600/1 = 8,600 miles/hr

Distance travelled by Space Explorer A in 10 hours = 70,000 miles

Speed (miles per hour) = 70,000/10 = 7,000 miles/hr

Compare the speed of both space explorers. The speed of Space Explorer B is greater than that of Space Explorer A by 1,600 miles/hr (8,600 - 7,000 = 1,600).

This means:

Space Explorer B travels 1,600 miles per hour faster than Space Explorer A.
