lilavasa [31]

<h3>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
