Total time traveled is equal to the sum of 2 minutes and 57 seconds.
Convert 2 minutes to hours and 57 seconds to hours. Then add the two times.
Then, Velocity = Distance/Time
[Note: The distance given is 2.03 miles.]
T1 = 2 min/(60 min) * 1 hour = .033 hr
T2 = 57 sec/(60 sec)*(1 min)/(60 min)* 1 hour = .016 hr
Total time, T, = T1 + T2 = .033 + .016 = .049
Velocity = 2.03 miles/(.049 hr)
= 41.43 miles per hour
Hope that helps.

------------------
rate = distance/time = 2.03 miles / 2 (57/60) minutes
= 2.03 miles/2.95 minutes
= 0.6881 miles per minute
