Her mother is 40 years old because 10 times 4 equals 40 because it’s adding 10 times in a row like 10 + 10 + 10 + 10 = 40
1 mile = 6.45 minutes
? miles = 30 minutes
? miles = 30 / 6.45 = 4.65116279 (round up)
4.7 miles = 30 minutes
So roughly 4 and a half miles in 30 minutes
Answer:
50
Step-by-step explanation:
Let the number be x
the question can be represented as
(32/100)x + 10 = 26
Therefore 0.32x + 10 = 26
0.32x = 26 -10
0.32x = 16
x = 16/0.32
x = 50
