How long would it take for an airplane to reach it’s destination if it traveled at an average speed of 790 km/hr for a distance of 5000 kilometers

This one is answered exactly like the one about the thunder and lightning that you posted a few minutes earlier.

Time = (distance covered) / (speed)

Time = (5,000 km) / (790 km/hr)

Time = 6.329 hours

That's 6 hours 19 minutes 44.8 seconds

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
