How long does it take to drive 1654 miles?

Answer 1

Time is inversely proportional to speed for this question.(i.e., As time goes down speed goes up)

Average Speed (s) = Distance (d) / Time (t)

s = d/t

Solve for t:

s = d/t
st = d

t = d/s (time is equal to distance divided by speed)

Since we know d, we can plug it in:

t = 1654/s

At 30 mph:

t = (1654 miles) / (30 miles/hour) = 51.13 hours

At 45 mph:

t = 1654/45 = 36.76 hours

At 60 mph:

t = 1654/60 = 27.57 hours
