a) The distance covered is 10 miles.
b) The distance covered is 15 miles.
Step-by-step explanation:
a)Driving home takes 15 minutes and with an average speed of 40 mph, what is the distance covered?
First we will convert the speed into per minute by dividing 60.
Speed = [tex]\frac{40}{60}=\frac{4}{6} \ miles\ per\ minute[/tex]
Time = 15 minutes
Distance = Speed*Time
Distance = [tex]\frac{4}{6}*15=\frac{60}{6}[/tex]
Distance = 10 miles
The distance covered is 10 miles.
b)Driving to work takes 20 minutes and with an average speed of 45 mph, what is the distance covered.
Speed = 45 mph = [tex]\frac{45}{60}=\frac{3}{4}\ miles\ per\ minute[/tex]
Time = 20 minutes
Distance = Speed * Time
Distance = [tex]\frac{3}{4}*20=\frac{60}{4}[/tex]
Distance = 15 miles
The distance covered is 15 miles.
