Answer:
2 hours
Step-by-step explanation:
Time, speed, and distance are related by ...
d = st
The distance covered is ...
d = (60 mi/h)(3 h) = 180 mi
Then the time taken at the higher speed is ...
180 mi = (60 mi/h +30 mi/h)(t)
t = (180 mi)/(90 mi/h) = 2 h
The time taken at the higher speed is 2 hours.
