Divide the time of Glenn's trip by the time of Shepard' trip.
Let's say Glenn's trip around the earth took about 5 hours. that is how many times as long as Shepard's flight?

ms. sue i got 12.49
15 minutes = 0.25 hour = time of Shepard's trip
5 / 0.25 = 20
Glenn's trip took 20 times as long.
5 / 0.25 = 20
Glenn's trip took 20 times as long.
