Question

2. An airplane travels 335

miles in 45 minutes.
How fast does it travel?
How fast is that in
km/hr?

Answer 1

The airplane travels at a speed of 446.67 mph and is equivalent to 718.53 km/hr.

Step-by-step explanation:

To find the speed of the airplane, we need to divide the distance traveled by the time taken. The distance traveled is 335 miles, and the time taken is 45 minutes. First, let's convert the time to hours by dividing it by 60, so 45 minutes is 0.75 hours. Now, we divide the distance by the time: 335 miles / 0.75 hours = 446.67 mph.

To convert this speed from miles per hour to kilometers per hour, we need to use the conversion factor of 1 mile = 1.60934 kilometers. So we multiply the speed in mph by the conversion factor: 446.67 mph * 1.60934 km/mi = 718.53 km/hr.

Answer 2

Answer: The answer is 716.8 km/hr

Step-by-step explanation:

The main idea here is the convert the given units to km and hr. Here's the conversion factors.

1mi= 1.6km

1hr= 60min

We have to multiply 335miles by 1.60km/mi in order to get the answer in km then again we have to multiply 45 minutes by 1hr/60min in order to get the answer in hr.

The last step is to calculate the speed using the formula : v=d/t

=537.6km/0.75hr

=716.8km/hr
