Answer:</h3>
= 633,600 Inches
<h3>
Explanation:</h3>
Speed refers to the rate of change in distance traveled by a body in motion.
It is the ratio of distance to time taken.
It is calculated by;
Speed = Distance ÷time taken
Therefore;
Distance = Speed × time
In this case;
Time taken = 12 minutes ( but 1 hr = 60 mins)
Thus, t = 0.2 hours
Speed = 50.0 miles/hour
Thus;
Distance = 50.0 miles/hr × 0.2 hours
= 10 miles
But, we are require to give the distance in inches;
1 mile = 63360 Inches
Therefore;
10 miles = 10 × 63360 Inches
= 633,600 Inches
Mass = 124 g
volume = 17 cm³
density = mass / volume
Therefore:
D = 124 / 17
D = 7.294 g/cm³
