An airplane flies with a constant speed of 560 miles per hour. How long will it take to travel a distance of 840 miles?​

t = 1.5 hours

Explanation:

Given that,

Speed of an airplane, v = 560 miles per hour

Distance, d = 840 miles

We need to find the time taken to cover a distance of 840 miles.

So, the required time is 1.5 hours.
