Answer :
The vehicle will travel a total of 80 miles in 1 hour and 20 minutes.
The vehicle is moving at a constant speed of 60 miles per hour.
It means that in one hour, the vehicle travels 60 miles.
So, we can write,
Miles travelled in hour = 60
Miles travelled in one minute = 60/60
Miles travelled in one minute = 1 mile
Total time given is 1 hours and 20 minutes.
1 hours = 60 minutes,
Hence, total time = 60+20
Total time = 80 minutes.
So, the distance travelled in 80 minutes = 80 x 80 miles,
Miles travelled in 80 minutes = 80 miles/
So, the vehicle travelled 80 miles in 1 hour and 20 minutes.
