Answer:

h x 60 = 60h minutes

Explanation:

In conversion questions involving algebra - try a few number examples for yourself first.

"How many minutes are there in 2 hours?" 2 x 60 = 120 minutes

"How many minutes are there in 4½ hours?" 4½ x 60 = 270 minutes

"How many minutes are there in 1/3 hour?" #1/3# x 60 = 20 minutes

From this we see that because there are 60 minutes in 1 hour, to change any number of hours into minutes involves "hours x 60"

Therefore the number of minutes in 'h' hours = h x 60 = 60h minutes
