121 ft    1 mile   60 sec   60 min
------- · -------- · --------· ---------  = 82.5 miles per hour 
1 sec    5280 ft   1 min    1 hour
 
121ft/sec is not as fast as 90 miles/hour

When learning to drive a car, I calculated that 60 mph was 88 ft/sec.  That is useful to know when thinking about stopping distance and how close to follow the car in front of me and ...
In this problem, 90 mph is 1.5 times that (so I calculated in my head 88+44 = 132 ft/sec for 90 mph  -- so it is faster.
