Answer:
Time = 82. 9 mins
Step-by-step explanation:
Given the following data;
Distance = 3.2 miles
Time = 2.4 hours to minutes = 2.4 * 60 = 144 mins
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the equation, we have;
[tex]Speed = \frac{3.2}{144}[/tex]
Speed = 0.0222 miles/min
Now, to find the time to walk 1.84 miles;
[tex]Time = \frac{distance}{speed}[/tex]
[tex]Time = \frac{1.84}{0.0222}[/tex]
Time = 82.9 mins (to 1 decimal point).
Method II
Let the new time = x
3.2 miles = 2.4 hours
1.84 miles = x hours
Cross-multiplying, we have;
3.2x = 2.4 * 1.84
3.2x = 4.416
x = 4.416/3.2
x = 1.38 hours
Now, we would convert the hours to minutes;
x = 1.38 * 60
x = 82.8 mins.
