Answer:
3.5 hours
Step-by-step explanation:
The buses are separating from each other at a speed of 73+79 = 152 miles per hour. Since time = distance/speed, the time it takes to be 532 miles apart is ...
time = (532 miles)/(152 miles/hour) = (532/152) hours = 3.5 hours
3.35 hours is 3 hours and 21 minutes.
3.35 hours is also equivalent to 201 minutes and 0 seconds or 12060 seconds.
Hope this helps!
Have a wonderful day!
