Question

if i'm traveling 78 miles per hour how long will it take to go 658 miles?

Answer 1

If you're traveling 78 miles per hour and you would like to travel a long 658 miles, then you just need to divide your total amount: 658 miles with your speed which is 78

this basically means
658 / 78 = 8.43

You will need around 8 hours to get there.
