Dana enjoys taking her dog for a walk, but sometimes her dog gets away and she has to run after him. dana walked her dog
for 7 miles but then had to run for 1 mile, spending a total time of 2.5 hours with her dog. her running speed was 3 mph
faster than her walking speed. find her walking speed.

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
