Your rate is 1.75 / 2.33 So to find the distance in 29 minutes we use the following formula.
d = rt
d = distance
r = rate
t = time
Plugin the numbers we know
r = rate = 1.75 / 2.33
t = time = 29 minutes
d = rt
d = (1.75 / 2.33) * 29
d = 21.78
In 29 minutes, the car will travel 21.78 miles
Do the same for the 1 hour. One hour = 60 minutes
d = rt
d = (1.75 / 2.33) * 60
d = 45.06
In 60 minutes, the car will travel 45.06 miles.
