Answer:

Then, the object will take 29.11 min to travel 4\frac{9}{10}miles

Step-by-step explanation:

When an object is moving at a steady speed, we can calculate the time it would take to travel a given distance using the following formula:

time=\frac{distance}{speed} (equation 1)

In this particular, both the given speed and distance are mixed fractions so we'll first convert them into improper fractions to operate more easily:

speed=10\frac{1}{10} \frac{mi}{h} =\frac{(10*10)+1}{10} \frac{mi}{h}=\frac{101}{10}  \frac{mi}{h}

distance=4\frac{9}{10}mi=\frac{(4*10)+9}{10}mi=\frac{49}{10}mi

So, now we can calculate the time using the equation 1:

time=\frac{distance}{speed}=\frac{\frac{49}{10}mi }{\frac{101}{10} \frac{mi}{h} } =\frac{49*10}{101*10} h

time=\frac{49}{101}h=0.49h

And, if we want the result in minutes:

time=\frac{49}{101}h*\frac{60min}{1h}  =29.11min

Then, the object will take 29.11 min to travel 4\frac{9}{10}miles
