20 minutes = 1/3 of an hour
1/3 = 0.333
1/3 x 45mph = 15, so she drove 15 miles at 45mph
18-15 = 3
3 miles/ 20 mph = 0.15 hours
0.333+0.15 = 0.483 hours total
0.483 x 60 = 28.98 so approximately 29 minutes total driving time
7:15 + 29 minutes is 7:44 am she arrived at work
2/7 = 10/35
1/5 = 7/35
10/35 + 7/35 = 17/35.
The solution to the problem is as follows:
9 3/4 = 9 *4/4 + 3/4 = 36/4 + 3/4 = 39/4
by making it a % that means you divide it by 100
for example 9 3/4 % = 0.0975
so 9 3/4 % = 39/4 * 1/100 = 39/400
