APPROACH #1: Formula
Time = distance/speed
= 350 miles/50 mph
= 7 hours

Answer: C

APPROACH #2: Common sense
Bob's speed is 50 miles per hour.
In other words, for every 1 hour that elapses, Bob travels 50 miles

So, after 1 hour of traveling, Bob has traveled 50 miles
After 2 hours of traveling, Bob has traveled 100 miles
After 3 hours of traveling, Bob has traveled 150 miles
After 4 hours of traveling, Bob has traveled 200 miles
After 5 hours of traveling, Bob has traveled 250 miles
After 6 hours of traveling, Bob has traveled 300 miles
After 7 hours of traveling, Bob has traveled 350 miles

Answer: C

Cheers,
Brent

Distance : 350 miles
Speed(Average) - 50 mph

Time taken = Distance/Speed

The total time taken is \(\frac{350}{50} = 7\)(Option C)

We can use the formula:

50 = 350/t

50t = 350

t = 7 hours
