1/50 of a mile is the distance the snail goes in 50 minutes. To get an hour, the snail must move for another 10 minutes (60-50=10).
Dividing 1/50 mile by 5 gives us 0.2/50 mile, which would be what the snail travels in 10 mins.
This can be added to 1/50 to give 1.2/50 mile as the answer
OR
You can take 0.2 and times it by 6 (to get 60 minutes from 10 minutes) to give the same answer as above.
Either way, the snail has gone 1.2 miles after the hour has passed.
Example
6.
3/8+1/4+__=1
1/4 is the same like 2/8
3/8+2/8=5/8
5/8+__=1
1 is the same like 8/8
5/8+__=8/8
8/8-5/8=_
8/8-5/8=3/8
Blank field-> 3/8
The equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³
<h3>How to use rule of exponents?</h3>
We are given the expression as;
(1.4³/1.2⁴)⁻⁶
Now, according to rule of exponents in multiplication, we know that;
x² × x³ = x² ⁺ ³ = x⁵
Thus, applying that rule of exponents above to our given problem and we have;
(1.4³/1.2⁴)⁻⁶ = (1.4³ ⁻ ⁶)/(1.2⁴ ⁻ ⁶)
⇒ 1.4⁻³/1.2⁻²
Also according to rule of exponents we know that;
x⁻¹ = 1/x
x⁻² = 1/x²
Thus;
1.4⁻³/1.2⁻² = (1/1.4³)/(1/1.2²)
⇒ 1.2²/1.4³
Thus, we can conclude about the question that the equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³
