Answer:
23 hours
Step-by-step explanation:
So here we are trying to calculate Time which is Distance divided by Speed
Time =
Firstly, we have to calculate the Speed which is = = 60
This means that the speed is 60 miles per hour or 60 mph.
Then to find the total time we take the Distance and divide it by the Speed:
= 35
So this means that his total trip took 35 hours so lets subtract 12 hours to get how many more hours: 35 - 12 = 23 hours
