Answer:
449/20 or 22 9/20
Step-by-step explanation:
Change them to mixed numbers.
55 x 5 = 275 + 1 = 276
32 x 4 = 128 + 3 = 131
Then, convert them to a common denominator.
276 x 4 = 1104
131 x 5 = 655
1104 - 655 = 449
449/20
Saturday and Sunday: 8 1/4 hours + 6 1/4 hours = 33/4 + 25/4 = 58/4 = 29/2 hours = 14 1/2 hours
A total of 88 1/2 miles = 177/2 miles for both days.
If you would like to know how long does it take him to ride one mile on his bike, you can calculate this using the following steps:
88 1/2 miles ... 14 1/2 hours
1 mile ... x hours = ?
88 1/2 * x = 1 * 14 1/2
177/2 * x = 29/2 /*2
177 * x = 29 /177
x = 29/177 hours
x = 0.16 hours
Result: It takes him 0.16 hours to ride one mile on his bike.
