Answer:
Will the printer work when I connect the printer's USB cable into a USB 2.0 port on my computer:
b. Yes, but at the USB 2.0 speed.
Explanation:
- The option a is not correct as we can use 2.0 port also for this purpose but not only 3.0.
- The option b is correct as we can use 2.0 USB Port for 3.0 USB but the speed will remain that of 2.0 USB.
- The option c is incorrect as because the speed is dependent on the speed of port.
- The option d is incorrect as because USB can have speed of 2.0 or 3.0 depending upon the port and USB but can't have 1.1 speed.
Answer:
float time_hourly=(time_min/60);
float speed_mph=(distance_mil/time_hourly);
Explanation:
I have taken a float variable time_hourly to convert the time given in minutes in hours.We need to divide the time in minutes by sixty since there are 60 minutes in an hour.
I have taken a float variable speed_mph to calculate the speed.Since we know the speed is distance/time and provided the distance is in miles and the time is in hours.
