A car moves with an average speed of 45 miles/hour. How long does the car take to travel 90 miles?
2 answers:
The car takes 2 hours to travel 90 miles
<h3><u>Answer;</u></h3>
<em>= 2 hours </em>
<h3>Solution;</h3>
Speed is the distance covered by a moving body per unit time.
Thus, speed = distance/time
Therefore; time will be given by distance divided by time
Hence; time =Distance/time
distance = 90 miles
speed = 45 miles/hour
Time = 90 miles/45 miles/hour
= 2 hours
Therefore, a time of two hours is taken by the car to travel 90 miles when moving at a speed of 45 miles/hour.

Roughly 13 degrees, specifically 13.3 repeating
7and 2 3rds divided by 5 and 3 8ths is more then one
The answer would be x=2/3
The answer is: y= –1/3x–5
