Ответ:
The time required is 1.2 hours
Step-by-step explanation:
The formula is
d= rt where d is the distance and r is the rate and t is time
85 miles per hour is the rate and 102 is the distance
102 = 85 miles per hour * t
Divide each side by 85
102/85 = 85t/85
1.2 = t
The time required is 1.2 hours
