Answer:he spent 1 hour driving at 55 mikes per hour
Step-by-step explanation:
Let x represent the time that Thomas spent driving at 30 miles per hour.
Let y represent the time that Thomas spent driving at 55 miles per hour.
Total time for the trip is 5 hours. This means that
x + y = 5
Distance = speed × time
Distance travelled at 30 miles per hour for x hours = 30×x = 30x miles
Distance travelled at 55 miles per hour for y hours = 55×y = 55y miles
If he traveled a distance of 250 miles, therefore
30x + 55y = 250 - - - - - - -1
Substituting x = 5 - y into equation 1, it becomes
30(5 - y) + 55y = 250
150 - 30y + 55y = 250
- 30y + 55y = 250 - 150
25y = 100
y = 100/25
y = 4
y = 5 - x = 5 - 4
y = 1
